RD0
bit 0
Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-0
RD<7:0>: PORTD General Purpose I/O Pin bits⁽¹⁾
1 = Port pin is > VIH
0 = Port pin is < VIL
Note 1: Writes to PORTD are actually written to the corresponding LATD register. Reads from the PORTD register
is return of actual I/O pin values.

bit 7-0
TRISD<7:0>: PORTD Tri-State Control bits
1 = PORTD pin configured as an input (tri-stated)
0 = PORTD pin configured as an output
