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 5-0

RA<5:0>

: PORTA I/O Value bits(1)

= Port pin is > VIH

= Port pin is < VIL

Note 1:

Writes to PORTA are actually written to corresponding LATA register. Reads from PORTA register is

return of actual I/O pin values.

Bit RA3 is read-only, and will read ‘1’ when MCLRE = 1 (master clear enabled).
