12.7 - Port 4
If this 8-bit port is used for general purpose I/O, the direction of each line can be configured via the
corresponding direction register DP4.
P4 (FFC8h / E4h)
DP4 (FFCAh / E5h)
For CAN configuration support (see section 15), Port 4 has an open drain function, controlled with the
ODP4 register:
ODP4 (F1CAh / E5h)
Note: Only bit 6 and 7 are implemented, all other bit will be read as “0”.

Port Data Register P4 Bit y
Port Direction Register DP4 Bit y
DP4.y = 0: Port line P4.y is an input (high-impedance)
DP4.y = 1: Port line P4.y is an output
Port 4 Open Drain Control Register Bit y
ODP4.y = 0: Port line P4.y output driver in push/pull mode
ODP4.y = 1: Port line P4.y output driver in open drain mode if P4.y is not a segment
address line output
