Texas Instruments MSP430x1xx manual Output Unit, 2. Output Modes, OUTMODx Mode Description

Timer_A Operation

11.2.5 Output Unit

Each capture/compare block contains an output unit. The output unit is used to generate output signals such as PWM signals. Each output unit has eight operating modes that generate signals based on the EQU0 and EQUx signals.

Output Modes

The output modes are defined by the OUTMODx bits and are described in Table 11−2. The OUTx signal is changed with the rising edge of the timer clock for all modes except mode 0. Output modes 2, 3, 6, and 7 are not useful for output unit 0 because EQUx = EQU0.

Table 11−2. Output Modes

OUTMODx	Mode	Description
000	Output	The output signal OUTx is defined by the
		OUTx bit. The OUTx signal updates
		immediately when OUTx is updated.
001	Set	The output is set when the timer counts
		to the TACCRx value. It remains set until
		a reset of the timer, or until another
		output mode is selected and affects the
		output.
010	Toggle/Reset	The output is toggled when the timer
		counts to the TACCRx value. It is reset
		when the timer counts to the TACCR0
		value.
011	Set/Reset	The output is set when the timer counts
		to the TACCRx value. It is reset when the
		timer counts to the TACCR0 value.
100	Toggle	The output is toggled when the timer
		counts to the TACCRx value. The output
		period is double the timer period.
101	Reset	The output is reset when the timer counts
		to the TACCRx value. It remains reset
		until another output mode is selected and
		affects the output.
110	Toggle/Set	The output is toggled when the timer
		counts to the TACCRx value. It is set
		when the timer counts to the TACCR0
		value.
111	Reset/Set	The output is reset when the timer counts
		to the TACCRx value. It is set when the
		timer counts to the TACCR0 value.
