120 / 398 page ![]() PIC12F/LF1822/16F/LF1823 DS41413A-page 120 Preliminary 2010 Microchip Technology Inc. 12.2.2 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 CapSense 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. RA0 1. ICSPDAT 2. ICDDAT 3. DACOUT (DAC) 4. MDOUT (PIC12F/LF1822 only) 5. TX/CK (EUSART) 6. SDO (PIC12F/LF1822 only) 7. P1B (PIC12F/LF1822 only) RA1 1. ICSPCLK 2. ICDCLK 3. SCL (PIC12F/LF1822 only) 4. RX/DT (EUSART) 5. SCK (PIC12F/LF1822 only) RA2 1. SRQ 2. C1OUT (Comparator) 3. SDA (PIC12F/LF1822 only) 4. CCP1/P1A (PIC12F/LF1822 only) RA3 No output priorities. Input only pin. RA4 1. OSC2 2. CLKOUT 3. T1OSO 4. CLKR 5. TX/CK (PIC12F/LF1822 only) 6. SDO 7. P1B (PIC12F/LF1822 only) RA5 1. OSC1 2. T1OSI (Timer1 Oscillator) 3. SRNQ (PIC12F/LF1822 only) 4. RX/DT (PIC12F/LF1822 only) 5. CCP1/P1A (PIC12F/LF1822 only) |
