CM11)
The functions associated with bits 2 and 1 (CM12 and CM11) of System Clock Control
Register 1 (CM1 at address 00007h) cannot be used. When writing to CM12 and CM11,
always be sure to write a “0”. This bit reads as “0” when read out.
After changing the bit 3 (CM13) of the System Clock Control Register 1 (CM1 at address
00007h) to “1”, do not set it to “0”. Otherwise, the emulator cannot be operated normally.
When using low-speed clock mode, always be sure to set the bit 3 (CM13) of the System
Clock Control Register 1 (CM1 at address 00007h) to “1” before setting bit 2 (OCD2) of
the Oscillation Stop Detection Register (OCD at address 0000Ch) to “0” (XIN clock
selected).
When using the internal clock as an XCIN clock source, built a desired oscillator circuit
on the included OSC-2 oscillator circuit bare board and replace the oscillator circuit
board on the emulator.
Choose “Internal” to main-clock and sub-clock in the Init dialog box of emulator tab after
starting up the emulator debugger. When using a clock on the user system, choose
“External” to main-clock and sub-clock.
This product does not support voltage monitor 0 reset and Voltage Monitor 0 Circuit
Control Register (VW0C at address 00038h).
Therefore, do not access the Voltage Monitor 0 Circuit Control Register.
This product supports only voltage monitor 1 reset, and does not support the voltage
monitor 1 interrupt. Therefore, when setting bit 0 (voltage monitor 1 interrupt/reset enable
bit: VW1C0) of the Voltage Monitor 1 Circuit Control Register (VW1C at address 00036h)
to “1”(= enable), always make sure that bit 6 (voltage monitor 1 circuit mode select bit:
VW1C6) is also set to “1”(= voltage monitor 1 circuit reset mode).
Be aware that the Port 1 Drive Capability Control Register (P1DRR at address 000FEh)
in this product is subject to limitations that although the drive capability of the n-channel
(Low side) output transistor can be increased, that of the p-channel (High side) output
transistor cannot be increased.
The function of bit 5 (LVD0ON) in the Option Function Select Register (OFS at address
0FFFFh) cannot be used. When writing to this register, always be sure to set LVD0ON to
“1”.
When you change the bit 7 (CSPROINI) of the Option Function Select Register (OFS at
address 0FFFFh), by rewriting directly or downloading, the reset operation from the
emulator should be done twice or more. Otherwise, the alteration may not be reflected.

- Note on using the timer RA Output pin (TRAO) function
- Note on access to the SFR area from the emulator debugger
- Note on the bit2 of the Pin Select Register 1 (PINSR1)
- Note on the bit5, bit2, bit1 and bit0 of the Pin Select Register 3 (PINSR3)
- Note on holding the error flags in serial interfaces
- Note on the High-Speed On-Chip Oscillator Control Register 4 (FRA4) and High-Speed
- Note on the High-Speed On-Chip Oscillator Control Register 7 (FRA7)
- Note on the Port Mode Register (PMR)
When using the port P3_7/TRAO/SSO/RXD1/(TXD1) pin as the TRAO pin function, set
the bit4 (reserved bit) of the Pin Select Register 2 (PINSR2: address 000F6h) to “1”
before using it. If you read out this register, “1” is read out after setting the bit to “1”.
Note that the SFR area can be accessed from the user program, as specified in the
program.
If you read out the bit2 (reserved bit) of the Pin Select Register 1 (PINSR1: address
000F5h), “0” is read out when resetting the MCU and “1” is read out when setting the bit2
to “1”. For the actual MCU, “0” is read out although “1” is set.
Before using the timer RC or timer RE, be sure to set the bit5, bit2, bit1 and bit0
(reserved bits) of the Pin Select Register 3 (PINSR3: address 000F7h) to “1”. If you read
out these reserved bits, “0” is read out when resetting the MCU and “1” is read out when
setting these bits to “1”. For the actual MCU, “0” is read out although “1” is set.
The clear conditions of the overrun error flag (OER) when using the clock synchronous
serial I/O mode and the clock asynchronous serial I/O (UART) mode, and the framing
error flag (FER) and the parity error flag (PER) when using the clock asynchronous serial
I/O (UART) mode are different form the actual MCU.

On-Chip Oscillator Control Register 6 (FRA6)
This product does not support High-Speed On-Chip Oscillator Control Register 4 (FRA4:
address 00029h) and High-Speed On-Chip Oscillator Control Register 6 (FRA6: address
0002Bh). If you read FRA4 or FRA6 register, an undefined value is read in. Do not
transfer the value to FRA1 register.
This product does not support High-Speed On-Chip Oscillator Control Register 7 (FRA7:
address 0002Ch). If you read FRA7 register, an undefined value is read in. Do not
transfer the value to FRA1 register.
The hardware manual says, 'If you write to the bit2 of the Port Mode Register (PMR:
address 000F8h), write “0”. When reading the value, “0” is read out.' However, with this
product, be sure to write “1” to the bit2 of the port mode register. When reading the value,
“1” is read out.
In the memory window, ASM watch window and script window of the emulator debugger,
if you reference or modify the SFR area in word, all the areas will be accessed by byte
except for some areas of the timer RC related register (00126h--0012Fh).
