Bits Name Value Description

15-4 Reserved 0 Reserved

3 SOCB SOCB Force Bit. The SOCB pulse will only be generated if the event is enabled in the ETSEL

0 Has no effect. Always reads back a 0.

1 Generates a pulse on EPWMxSOCB and sets the SOCBFLG bit. This bit is used for test purposes.

2 SOCA SOCA Force Bit. The SOCA pulse will only be generated if the event is enabled in the ETSEL

0 Writing 0 to this bit will be ignored. Always reads back a 0.

1 Generates a pulse on EPWMxSOCA and set the SOCAFLG bit. This bit is used for test purposes.

1 Reserved 0 Reserved

0 INT INT Force Bit. The interrupt will only be generated if the event is enabled in the ETSEL register.

The INT flag bit will be set regardless.

0 Writing 0 to this bit will be ignored. Always reads back a 0.

1 Generates an interrupt on EPWMxINT and set the INT flag bit. This bit is used for test purposes.
