6.4.4 Timer
Effects of STOP and WAIT on the timer are discussed here.
6.4.4.1 STOP
The STOP instruction:
Clears the RTIE, TOFE, RTIF, and TOF bits in the timer status and
control register, disabling timer interrupt requests and removing
any pending timer interrupt requests
Disables the clock to the timer
After exiting stop mode by external interrupt, the timer immediately
resumes counting from the last value before the STOP instruction and
continues counting throughout the oscillator stabilization delay.
After exiting stop mode by reset and after the oscillator stabilization
delay, the timer resumes operation from its reset state.
6.4.4.2 WAIT
The WAIT instruction has no effect on the timer.
6.4.5 EPROM/OTPROM
Effects of STOP and WAIT on the EPROM/OTPROM are discussed
here.
6.4.5.1 STOP
The STOP instruction during EPROM programming clears the EPGM bit
in the EPROM programming register, removing the programming
voltage from the EPROM.
6.4.5.2 WAIT
The WAIT instruction has no effect on EPROM/OTPROM operation.
