PORTA FUNCTIONS AND OUTPUT

PRIORITIES

Each PORTA pin is multiplexed with other functions. The

pins, their combined functions and their output priorities

are briefly described here. For additional information,

refer to the appropriate section in this data sheet.

When multiple outputs are enabled, the actual pin

control goes to the peripheral with the lowest number in

the following lists.

Analog input functions, such as ADC, comparator and

Cap Sense inputs, are not shown in the priority lists.

These inputs are active when the I/O pin is set for

Analog mode using the ANSELx registers. Digital

output functions may control the pin when it is in Analog

mode with the priority shown below.
