Bits 26:24 – UPDMOD[2:0] PWM Buffer Update Mode Selection bits

See Table 15-10 for details.

Bits 23:22 – TRGMOD[1:0] PWM Generator x Trigger Mode Selection bits⁽⁴⁾

Value	Description
11	Reserved
10	Reserved
01	PWM Generator operates in Retriggerable mode
00	PWM Generator operates in Single Trigger mode

Bits 19:16 – SOCS[3:0] Start-of-Cycle Selection bits⁽⁴⁾

Note:

The PCI selected Sync signal is always available to be OR’d with the selected SOC signal per the SOCS[3:0] bits if the PCI Sync function is enabled.
The source selected by the SOCS[3:0] bits MUST operate from the same clock source as the local PWM Generator. If not, the source must be routed through the PCI Sync logic so the trigger signal may be synchronized to the PWM Generator clock domain.
PWM Generators are grouped into groups of four: PG1-PG4 and PG5-PG8, if available. Any generator within a group of four may be used to trigger another generator within the same group.

Value	Description
`1111`	TRIG bit or PCI Sync function only (no hardware trigger source is selected)
`1110 -0101`	Reserved
`0100`	Trigger output selected by PG4 or PG8 PGTRGSEL[2:0] bits (PGxEVT[2:0])
`0011`	Trigger output selected by PG3 or PG7 PGTRGSEL[2:0] bits (PGxEVT[2:0])
`0010`	Trigger output selected by PG2 or PG6 PGTRGSEL[2:0] bits (PGxEVT[2:0])
`0001`	Trigger output selected by PG1 or PG5 PGTRGSEL[2:0] bits (PGxEVT[2:0])
`0000`	Local EOC – PWM Generator is self-triggered

Bit 15 – ON PWM Generator x Enable bit⁽¹⁾

Value	Description
`1`	PWM Generator is enabled
`0`	PWM Generator is not enabled

Value	Description
`111`	PWM Generator produces 8 PWM cycles after triggered
`110`	PWM Generator produces 7 PWM cycles after triggered
`101`	PWM Generator produces 6 PWM cycles after triggered
`100`	PWM Generator produces 5 PWM cycles after triggered
`011`	PWM Generator produces 4 PWM cycles after triggered
`010`	PWM Generator produces 3 PWM cycles after triggered

Bits 4:3 – CLKSEL[1:0] Clock Selection bits⁽¹⁾

Note:

Do not change the CLKSEL[1:0] bits while ON (PGxCON[15]) = 1.
The PWM Generator time base operates from the frequency scaling circuit clock, effectively scaling the duty cycle and period of the PWM Generator output.

Value	Description
`11`	PWM Generator uses the master clock scaled by the frequency scaling circuit⁽²⁾
`10`	PWM Generator uses the master clock divided by the clock divider circuit⁽²⁾
`01`	PWM Generator uses the master clock selected by the MCLKSEL[1:0] (PCLKCON[1:0]) control bits
`00`	No clock selected, PWM Generator is in the lowest power state (default)
