CHAPTER 7 8-BIT PWM TIMER

8-bit PWM timer registers
Figure 7.3-2 8-bit PWM timer registers
Note:
As the PWM compare register (COMR) is write-only, the bit manipulation instructions cannot be used.
■
8-bit PWM timer interrupt source
IRQ2:
For the interval timer function, the 8-bit PWM timer generates an interrupt request if interrupt request
output is enabled (CNTR: TIE = "1") when the counter value matches the value set in the COMR
register. (For PWM function, no interrupt request is generated.)
