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 7-5
bit 4
bit 3-0
LATB<7:5>: Dedicated the LIN Transceiver Transmit Function⁽¹⁾
LATB4: RB4 Port I/O Output Latch Register bit⁽¹⁾
Unimplemented: Read as ‘0’
Note 1: Writes to PORTB are actually written to the corresponding LATB register. Reads from the PORTB register
actually return the I/O pin values.

ANSB<7:5>: Analog Select between Analog or Digital Function on Pins RB<7:5>
0 = Must be set to ‘0’. Digital I/O. Pin is assigned to port or digital special function.
1 = Not used
ANSB4: Analog Select between Analog or Digital Function on Pin RB4
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input⁽¹⁾. Digital input buffer is disabled.
Unimplemented: Read as ‘0’
Note 1: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
