Description
[7:0]
Pulse Width Modulator 0 High and Low Bytes
PWM0H, These two bytes, {PWM0H[7:0], PWM0L[7:0]}, form a 16-bit value that is compared to the
PWM0L 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).
The TxPWM0H and TxPWM0L registers also store the 16-bit captured timer value when
operating in CAPTURE, CAPTURE/COMPARE and DEMODULATION Modes.
9.3.4. Timer 0–2 PWM1 High and Low Byte Registers
The Timer 0–2 PWM1 High and Low Byte (TxPWM1H and TxPWM1L) registers, shown
in Tables 61 and 62, store Capture values for DEMODULATION Mode.
