Bit 7 – EVGEN Event Generation

Writing this bit to ‘1’ will output 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 this bit to ‘1’ will allow 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 is used to set the initial output value of the pin 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 or not.

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
