Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-6
bit 5-3
bit 2
bit 1-0
Unimplemented: Read as ‘0’
RA<5:3>: PORTA I/O Pin bit⁽¹⁾
1 = Port pin is > VIH
0 = Port pin is < VIL
Unimplemented: Read as ‘0’
RA<1:0>: PORTA I/O Pin bit
1 = Port pin is > VIH
0 = Port pin is < VIL
Note 1: The RA3 bit is only available when Master Clear Reset is disabled (MCLRE Configuration bit = 0).
Otherwise, RA3 reads as ‘0’. This bit is read-only.

TRISA<5:4>: PORTA Tri-State Control bit
1 = PORTA pin configured as an input (tri-stated)
0 = PORTA pin configured as an output
Unimplemented: Read as ‘0’
Note 1: TRISA<5:4> always reads ‘1’ in XT, HS and LP Oscillator modes.
