136 / 496 page  PIC18(L)F2X/4XK22 DS41412C-page 136 Preliminary 2010 Microchip Technology Inc. 10.1.1 PORTA OUTPUT PRIORITY 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 higher priority. Table 10-4 lists the PORTA pin functions from the highest to the lowest priority. Analog input functions, such as ADC and comparator, 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.
