Bit 7 – EVGEN Event Generation

Writing a ‘1’ to this bit generates the waveform output on the event line instead of the compare match. The CCMPEN bit is ignored for the event output.

Value	Name	Description
0	PULSE	An event pulse is generated when there is a compare match or capture
1	WAVEFORM	The event output is equal to the waveform output for modes where there is waveform output

Bit 6 – ASYNC Asynchronous Enable

Writing a ‘1’ to this bit allows asynchronous updates of the TCB output signal in Single-Shot mode.

Value	Description
0	The output will go HIGH when the counter starts after synchronization
1	The output will go HIGH when an event arrives

Bit 5 – CCMPINIT Compare/Capture Pin Initial Value

This bit sets the initial output pin value when a pin output is used. This bit has no effect in 8-bit PWM mode and Single-Shot mode.

Value	Description
0	Initial pin state is LOW
1	Initial pin state is HIGH

Bit 4 – CCMPEN Compare/Capture Output Enable

This bit controls whether the waveform output on the pin corresponding to WO is enabled.

Value	Description
0	Waveform output is not enabled on the corresponding pin
1	Waveform output is enabled and will be available on the pin corresponding to WO, which will override the configuration in the I/O Configuration (PORT) peripheral and automatically set the direction of the corresponding pin to output.

Bits 2:0 – CNTMODE[2:0] Timer Mode

Writing to this bit field selects the Timer mode.

Value	Name	Description
0x0	INT	Periodic Interrupt mode
0x1	TIMEOUT	Time-Out Check mode
0x2	CAPT	Input Capture on Event mode
0x3	FRQ	Input Capture Frequency Measurement mode
0x4	PW	Input Capture Pulse-Width Measurement mode
0x5	FRQPW	Input Capture Frequency and Pulse-Width Measurement mode
0x6	SINGLE	Single-Shot mode
0x7	PWM8	8-bit PWM mode
