bit 7
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 7-4
bit 3-0
RB<7:4>: PORTB I/O Value bits⁽¹⁾
1 = Port pin is > VIH
0 = Port pin is < VIL
Unimplemented: Read as ‘0’
Note 1: Writes to PORTB are actually written to corresponding LATB register. Reads from PORTB register is
return of actual I/O pin values.
