A.
XCLKOUT = SYSCLKOUT
B.
TxCTRIP – T1CTRIP, T2CTRIP, T3CTRIP, T4CTRIP
CxTRIP – C1TRIP, C2TRIP, C3TRIP, C4TRIP, C5TRIP, or C6TRIP
PDPINTx – PDPINTA or PDPINTB
C.
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.
