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 TPOL bit in the Timer Control 1 Register (TxCTL1) regis-
ter.
The TxPWMH and TxPWML registers also store the 16-bit captured timer value when
operating in CAPTURE or CAPTURE/COMPARE modes.
The Timer 0-3 Control 0 (TxCTL0) registers (see
of the Timers.
