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 7-4

RB<7:4>: PORTB General Purpose I/O Pin bits

1 = Port pin is > VIH

0 = Port pin is < VIL

bit 3-0

Unimplemented: Read as ‘0’

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-4

TRISB<7:4>: PORTB Tri-State Control bits

1 = PORTB pin configured as an input (tri-stated)

0 = PORTB pin configured as an output

LATB<7:4>: PORTB Output Latch Value bits(1)

bit 3-0

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.
