Pulse Width Modulator (PWM)
Register 23: PWM0 Counter (PWM0COUNT), offset 0x054
Register 24: PWM1 Counter (PWM1COUNT), offset 0x094
Register 25: 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 the load register, a pulse is output;
this can drive the generation of a PWM signal (via the PWMnGENA/PWMnGENB registers, see
page 445 and page 447) or drive an interrupt (via the PWMnINTEN register, see page 438). A pulse
with the same capabilities is generated when this value is zero.

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.
The current value of the counter.
