Timer 0-3 PWM High and Low Byte Registers
The Timer 0-3 PWM High and Low Byte (TxPWMH and TxPWML) registers (Tables 42
and 43) are used for Pulse-Width Modulator (PWM) operations. These registers also store
the Capture values for the Capture and Capture/Compare modes.

PWMH and PWML—Pulse-Width Modulator High and Low Bytes
These two bytes, {PWMH[7:0], PWML[7:0]}, form a 16-bit value that is compared to the
current 16-bit timer count. When a match occurs, the PWM output changes state. The
PWM output value is set by the TPOLbit in the Timer Control Register (TxCTL) register.
The TxPWMH and TxPWML registers also store the 16-bit captured timer value when
operating in Capture or Capture/Compare modes.
