C.6.4 PWM Counter Register
The read-only PWM counter register (PWMCR) holds the current count value. It can
be read at any time without disturbing the counter.
PWMCR0 — PWM0 Counter Register
PWMCR1 — PWM1 Counter Register
PWMCR2 — PWM2 Counter Register
PWMCR3 — PWM3 Counter Register
PWMCR4 — PWM4 Counter Register
PWMCR5 — PWM5 Counter Register

C.7.1 Edge Port Pin Assignment Register (EPPAR)
The 16-bit read/write edge port pin assignment register (EPPAR) configures each of
the interrupt pins as either level-sensitive or edge-sensitive. Rising, falling, or both
edges can be selected as the active edge. Requests are always generated out of this
block but may be masked within the interrupt controller module. The functionality of
this register is independent of the programmed pin direction.
