PIC10(L)F320/322
DS41585A-page 78 Preliminary  2011 Microchip Technology Inc.
REGISTER 10-3: LATA: PORTA DATA LATCH REGISTER
U-0 U-0 U-0 U-0 U-0 R/W-x/u R/W-x/u R/W-x/u
— — — — — 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 7-3 Unimplemented: Read as ‘0’
bit 2-0 LATA<2:0>: RA<2:0> Output Latch Value bits
Note 1: Writes to PORTx are actually written to the corresponding LATx register. Reads from LATx register return
register values, not I/O pin values.
REGISTER 10-4: ANSELA: PORTA ANALOG SELECT REGISTER
U-0 U-0 U-0 U-0 U-0 R/W-1/1 R/W-1/1 R/W-1/1
— — — — — 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 7-3 Unimplemented: Read as ‘0’
bit 2-0 ANSA<2:0>: Analog Select between Analog or Digital Function on Pins RA<2:0>, respectively
1 = Analog input. Pin is assigned as analog input
(1)
. Digital Input buffer disabled.
0 = Digital I/O. Pin is assigned to port or Digital special function.
Note 1: Setting a pin to an analog input automatically disables the digital input circuitry. Weak pull-ups, if
available, are unaffected. The corresponding TRIS bit must be set to Input mode by the user in order to
allow external control of the voltage on the pin.
