Timer 0 PWM High and Low Byte Registers
The Timer 0 PWM High and Low Byte (T0PWMH and T0PWML) registers, shown in
Tables 62 and 63, define Pulse-Width Modulator (PWM) operations. These registers also
store the timer counter values for the Capture modes.
The 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 (T0CTL1).
The T0PWMH and T0PWML registers also store the 16-bit captured timer value when
operating in CAPTURE or CAPTURE/COMPARE modes.
