and output modes using the P0 port input/output control register (P0CR). When reset, the P0CR register is initialized
to 0, with the P0 port set for input mode. Also, the output latch (P0DR) is initialized to 0 when reset.
is used to select open-drain or tri-state mode for the port. When reset, the P0ODE register is initialized to 0, with tri-
state mode selected for the port.

Port P0 is a 4-bit input/output port shared with serial interface input/output. This port is switched between input
The P0 port contains bitwise programmable open-drain control. The P0 port open-drain control register (P0ODE)
Note 1: Even when open-drain mode is selected, the protective diode remains connected. Therefore, do not apply voltages
Note 2: Read-Modify-Write (RMW) operation executes at open-drain mode is selected, read out the output latch states.
Note 3: *: Don’t care

When any other instruction is executed, external pin states is read out.
