PIC16(L)F1516/7/8/9
REGISTER 12-4: LATA: PORTA DATA LATCH REGISTER
R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u R/W-x/u
LATA7 LATA6 LATA5 LATA4 LATA3 LATA2 LATA1 LATA0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-4 LATA<7:0>: PORTA Output Latch Value bits
(1)
Note 1: Writes to PORTA are actually written to corresponding LATA register. Reads from PORTA register is the
return of actual I/O pin values.
REGISTER 12-5: ANSELA: PORTA ANALOG SELECT REGISTER
U-0 U-0 R/W-1/1 U-0 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1
— — ANSA5 — ANSA3 ANSA2 ANSA1 ANSA0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-6 Unimplemented: Read as ‘0’
bit 5 ANSA5: Analog Select between Analog or Digital Function on pins RA5, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
(1)
. Digital input buffer disabled.
bit 4 Unimplemented: Read as ‘0’
bit 3-0 ANSA<3:0>: Analog Select between Analog or Digital Function on pins RA<3:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
(1)
. Digital input buffer disabled.
Note 1: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
