The maximum ROM capacity supported by this product is 112 Kbytes. You cannot debug
a program larger than 112 Kbytes (20000h—23FFFh). The following shows the Flash
Memory Block Diagram for when using with this product, taking the R8C/2C and /2D
Groups as an example.

- Note on the port XIN-XOUT switch bit (CM13)
- Note on the High-Speed On-Chip Oscillator Control Register 6 (FRA6)
- Note on the High-Speed On-Chip Oscillator Control Register 7 (FRA7)
- Note on the voltage monitor 0 reset
- Note on the voltage monitor 1 interrupt
- Note on the Port P2 Drive Capacity Control Register (P2DRR)
- Note on the voltage detection 0 circuit start bit (LVD0ON)
- Note on changing the count source protection mode after reset select bit (CSPROINI)
- Note on access to the SFR area from the emulator debugger
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.
This product does not support High-Speed On-Chip Oscillator Control Register 6 (FRA6:
address 0002Bh). If you read 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.
This product does not support the voltage monitor 0 reset and the 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 P2 drive capacity control register (P2DRR at address 000F4h) 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 in the memory window or downloading, the reset
operation from the emulator debugger should be done twice or more. Otherwise, the
alteration may not be reflected.
In the memory window, ASM watch window and script window of the emulator debugger,
if you reference or modify the SFR area in word unit, all the areas will be accessed by
byte except for some areas of the timer RC related registers (00126h--0012Fh).
Note that the SFR area can be accessed from the user program, as specified in the
program.
