• Manufacturer: EMC [ELAN Microelectronics Corp]

This specification is subject to change without prior notice.
4.2 Special Purpose Registers
8. R10 ~ R2F
1. A (Accumulator)
2. CONT (Control Register)
• Bits 3 ~ 7 Not used.
• RF can be cleared by instruction but cannot be set.
• IOCF is the interrupt mask register.
• Note that the result of reading RF is the "logic AND" of RF and IOCF.
• All of these are the 8-bit general-purpose registers.
• Internal data transfer, or instruction operand holding
• It can not be addressed.
• Bit 0 (PSR0) ~ Bit 2 (PSR2) TCC/WDT prescaler bits.
• Bit 3 (PAB) Prescaler assignment bit.
• Bit 4 (TE) TCC signal edge
• Bit 5 (TS) TCC signal source
• Bit 6 (INT) Interrupt enable flag
0: TCC
1: WDT
0: increment if the transition from low to high takes place on TCC pin
1: increment if the transition from high to low takes place on TCC pin
0: internal instruction cycle clock
1: transition on TCC pin
When TS is 1, the R62 I/O control bit will set to 1; otherwise, it will be the value defined by user.
0: masked by DISI or hardware interrupt
