Since the PxA and PxB outputs are multiplexed with the PORT data latches, the associated TRIS bits must be cleared to configure PxA and PxB as outputs.

The Alternate Pin Function Control 0 (APFCON0) and Alternate Pin Function Control 1 (APFCON1) registers are used to steer specific peripheral input and output functions between different pins. The APFCON0 and APFCON1 registers are shown in Register 12-1 and Register 12-2. For this device family, the following functions can be moved between different pins.

• RX/DT/TX/CK
• SDO1
• SS (Slave Select)
• T1G
• P1B/P1C/P1D/P2B
• CCP1/P1A/CCP2

These bits have no effect on the values of any TRIS register. PORT and TRIS overrides will be routed to the correct pin. The unselected pin will be unaffected.

• Note 1: This is the limit to which VDD can be lowered in Sleep mode without losing RAM data.
• 2: PLL required for 32 MHz operation.

Note 1: Power dissipation is calculated as follows: PDIS = VDD x {IDD - IOH} + {(VDD - VOH) x IOH} + (VOl x IOL).

† NOTICE: Stresses above those listed under 'Absolute Maximum Ratings' may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure above maximum rating conditions for extended periods may affect device reliability.

Note 1: IDD is current to run the chip alone without driving any load on the output pins.

2: TA = Ambient Temperature, TJ = Junction Temperature.
