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

TRISB<7:6>: PORTB Tri-State Control bits
Initialize as 0 = PORTB pin configured as an output
TRISB<5:4>: PORTB Tri-State Control bits
Initialize as 1 = PORTB pin configured as an input (tri-stated)
Unimplemented: Read as ‘0’
