TCIF
“1” means interrupt request, and “0” means no interrupt occurs.
Bit 0 (TCIF) TCC overflow interrupt flag. Set when TCC overflows, reset by software.
Bit 1 (ICIF) Port 6 input status change interrupt flag. Set when Port 6 input changes, reset by
software.
Bit 2 (EXIF) External interrupt flag. Set by falling edge on /INT pin, reset by software.
Bit 3 (ADIF) Interrupt flag for analog to digital conversion. Set when AD conversion is completed,
reset by software.
Bit 4 (PWM1IF) PWM1 (Pulse Width Modulation) interrupt flag. Set when a selected period is
reached, reset by software.
Bit 5 (PWM2IF) PWM2 (Pulse Width Modulation) interrupt flag. Set when a selected period is
reached, reset by software.
Bit 6 (CMPIF) High-compared interrupt flag. Set when a change occurs in the output of Comparator,
reset by software.
Bit 7 Unemployed, read as ‘0’;
RF can be cleared by instruction but cannot be set.
IOCF0 is the interrupt mask register.
Note that to read RF will result to "logic AND" of RF and IOCF0.
15. R10 ~ R3F
All of these are 8-bit general-purpose registers.
4.2 Special Purpose Registers
1. A (Accumulator)
Internal data transfer, or instruction operand holding
It can not be addressed.
