Pulse Width Modulator for Motor Control (PWMMC)
9.11 Control Logic Block
9.11.1 PWM Counter Registers
Technical Data

PCNTH
The following subsections provide a description of the control logic
block.
This PWM counter register displays the12-bit up/down or up-only
counter. When the high byte of the counter is read, the lower byte is
latched. PCNTL will hold this latched value until it is read.
