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 Register (TxCTL) register.
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
CSC—Cascade Timers
0 = Timer Input signal comes from the pin.
1 = For Timer 0, input signal is connected to Timer 1 output.
For Timer 1, input signal is connected to Timer 0 output.
