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 (TxCTL1)
register.
The TxPWMH and TxPWML registers also store the 16-bit captured timer value when
operating in CAPTURE or CAPTURE/COMPARE modes.
Time 0–1 Control Register 0
The Timer Control Register 0 (TxCTL0) and Timer Control Register 1 (TxCTL1)
determine the timer operating mode. It also includes a programmable PWM deadband
delay, two bits to configure timer interrupt definition, and a status bit to identify if the
most recent timer interrupt is caused by an input Capture event.
TMODEHI—Timer Mode High Bit
This bit along with the TMODE field in TxCTL1 register determines the operating mode
of the timer. This is the most-significant bit of the Timer mode selection value. See the
TxCTL1 register description for more details.
TICONFIG—Timer Interrupt Configuration
This field configures timer interrupt definition.
