Bit 31 – TRGD PGxTRIGD Kick-Off bit

Value	Description
1	PGxTRIGD compare event will trigger LEB duration counter.
`0`	LEB ignores PGxTRIGD compare event.

Bit 30 – TRGC PGxTRIGC Kick-Off bit

Value	Description
`1`	PGxTRIGC compare event will trigger LEB duration counter.
`0`	LEB ignores PGxTRIGC compare event.

Bit 29 – TRGB PGxTRIGB Kick-Off bit

Value	Description
`1`	PGxTRIGB compare event will trigger a LEB duration counter.
`0`	LEB ignores the PGxTRIGB compare event.

Bit 28 – TRGA PGxTRIGA Kick-Off bit

Value	Description
`1`	PGxTRIGA compare event will trigger the LEB duration counter.
`0`	LEB ignores PGxTRIGA compare event.

Bit 27 – PHR PWMx Rising Edge Trigger Enable bit

Value	Description
`1`	Rising edge of PWMx will trigger the LEB duration counter.
`0`	LEB ignores the rising edge of PWMx.

Bit 26 – PHF PWMxH Falling Edge Trigger Enable bit

Value	Description
`1`	Falling edge of PWMx will trigger the LEB duration counter.
`0`	LEB ignores the falling edge of PWMx.

Bit 25 – PLR PWMx Rising Edge Trigger Enable bit

Value	Description
`1`	Rising edge of PWMx will trigger the LEB duration counter.
`0`	LEB ignores the rising edge of PWMx.

Bit 24 – PLF PWMx Falling Edge Trigger Enable bit

Value	Description
`1`	Falling edge of PWMx will trigger the LEB duration counter.
`0`	LEB ignores the falling edge of PWMx.

Bits 19:4 – LEB[19:4] Leading-Edge Blanking Period bits

These bits select the leading edge blanking period. The 4 LSbs of the blanking time are not implemented, providing a blanking resolution of TPWMCLK. The LEB period is (LEB[15:4]+1)*TPWMCLK. The minimum blanking period is 5, values 0,1,2,3,4 all get LEB period of 5*TPWMCLK.

Note: TPWMCLK = 1/F_{PGx_clk}
