I/O ports, POEG, GPT, AGT, ULPT and ADC trigger timing (1 of 4)

GPT32 Conditions:

Middle drive output is selected in the Port Drive Capability bit in the PmnPFS register.

If GPT pins are specified across the VCC I/O and VCC2 I/O, characteristics below is guaranteed only when VCC = VCC2.

AGT Conditions:

Middle drive output is selected in the Port Drive Capability bit in the PmnPFS register.
