Pulse Width Modulator (PWM)
Register 27: PWM0 Counter (PWM0COUNT), offset 0x054
Register 28: PWM1 Counter (PWM1COUNT), offset 0x094
Register 29: PWM2 Counter (PWM2COUNT), offset 0x0D4
These registers contain the current value of the PWM counter (PWM0COUNT is the value of the
PWM generator 0 block, and so on). When this value matches zero or the value in the PWMnLOAD,
PWMnCMPA, or PWMnCMPB registers, a pulse is output which can be configured to drive the
generation of a PWM signal or drive an interrupt or ADC trigger.
PWM0 Counter (PWM0COUNT)
PWM0 base: 0x4002.8000

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Counter Value
The current value of the counter.
