123 / 456 page  2010 Microchip Technology Inc. DS41303G-page 123 PIC18F2XK20/4XK20 TABLE 10-2: SUMMARY OF REGISTERS ASSOCIATED WITH PORTA OSC1/CLKIN/RA7 RA7 0 O DIG LATA<7> data output. Disabled in external oscillator modes. 1 I TTL PORTA<7> data input. Disabled in external oscillator modes. OSC1 x I ANA Main oscillator input connection. CLKIN x I ANA Main clock input connection. Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Reset Values on page PORTA RA7(1) RA6(1) RA5 RA4 RA3 RA2 RA1 RA0 62 LATA LATA7(1) LATA6(1) PORTA Data Latch Register (Read and Write to Data Latch) 62 TRISA TRISA7(1) TRISA6(1) PORTA Data Direction Control Register 62 ANSEL ANS7(2) ANS6(2) ANS5(2) ANS4 ANS3 ANS2 ANS1 ANS0 62 SLRCON — — — SLRE(2) SLRD(2) SLRC SLRB SLRA 63 CM1CON0 C1ON C1OUT C1OE C1POL C1SP C1R C1CH1 C1CH0 62 CM2CON0 C2ON C2OUT C2OE C2POL C2SP C2R C2CH1 C2CH0 62 CVRCON CVREN CVROE CVRR CVRSS CVR3 CVR2 CVR1 CVR0 61 Legend: — = unimplemented, read as ‘0’. Shaded cells are not used by PORTA. Note 1: RA<7:6> and their associated latch and data direction bits are enabled as I/O pins based on oscillator configuration; otherwise, they are read as ‘0’. 2: Not implemented on PIC18F2XK20 devices. TABLE 10-1: PORTA I/O SUMMARY (CONTINUED) Pin Function TRIS Setting I/O I/O Type Description Legend: DIG = Digital level output; TTL = TTL input buffer; ST = Schmitt Trigger input buffer; ANA = Analog level input/output; x = Don’t care (TRIS bit does not affect port direction or is overridden for this option). |
