XCLKOUT = SYSCLKOUT

TxCTRIP – T1CTRIP, T2CTRIP, T3CTRIP, T4CTRIP

CxTRIP – C1TRIP, C2TRIP, C3TRIP, C4TRIP, C5TRIP, or C6TRIP

PDPINTx – PDPINTA or PDPINTB

PWM refers to all the PWM pins in the device (that is, PWMn and TnPWM pins or PWM pin pair relevant to each

CxTRIP pin). The state of the PWM pins after PDPINTx is taken high depends on the state of the FCOMPOE bit.
