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
RB<7:0>: PORTB I/O Pin bit
1 = Port pin is > VIH
0 = Port pin is < VIL

LATB<7:0>: PORTB Output Latch Value bits⁽¹⁾
Note 1: Writes to PORTB are actually written to corresponding LATB register. Reads from PORTB register is
return of actual I/O pin values.

Note 1:
2:
WPUB<7:0>: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
Global WPUEN bit of the OPTION register must be cleared for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in configured as an output.
