6.6.4.6 PWM-Timer Interrupt Architecture
NuMicro M051
At this case, the CNR is 8:
1.
2.
3.
There are eight PWM interrupts, PWM0_INT~PWM7_INT, which are divided into PWMA_INT and
PWMB_INT for Advanced Interrupt Controller (AIC). PWM 0 and Capture 0 share one interrupt,
PWM1 and Capture 1 share the same interrupt and so on. Therefore, PWM function and Capture
function in the same channel cannot be used at the same time. The Figure 6.6-15 demonstrates
the architecture of PWM-Timer interrupts.
The PWM counter will be reloaded with CNRx when a capture interrupt flag (CAPIFx) is set.
The channel low pulse width is (CNR + 1 – CRLR).
The channel high pulse width is (CNR + 1 – CFLR).
