Port 4 is an I/O port with an output latch. Port 4 can be set to the input mode or output mode in 1-bit units using port
This port can also be used for flash memory programmer/debugger data I/O and clock output.
Reset signal generation sets port 4 to input mode.
Figures 5-9 and 5-10 show block diagrams of port 4.
Note When a tool is connected, the P40 and P41 pins cannot be connected to a pull-up resistor.
Caution When a tool is connected, the P40 pin cannot be used as a port pin.
When the on-chip debug function is used, the P41 pin can be used as follows by the mode setting on
the debugger.
1-line mode: can be used as a port (P41).
2-line mode: used as a TOOL1 pin and cannot be used as a port (P41).
