used as the serial bus interface input/output, the serial interface input/output, the UART input/output and the on-
chip debug function.
MOS output can be selected. Port P2 contains a programmable pull-up resistor on the VDD side. This pull-up
resistor can be used when the port is used in the input mode or as a sink open drain output.
selecting function is also needed. For details, refer to "8.4 Serial Interface Selecting Function".
Port P2 (P25 to P20)
Port P2 is an 6-bit input/output port that can be set to input or output for each bit individually, and it is also
The output circuit has the P-channel output control function and either the sink open drain output or the C-
When this port is used as the serial bus interface, the serial interface or the UART, setting for serial interface
For the on-chip debug function, refer to the chapter of "On-chip Debug Function (OCD)".
