4.2.5 Port 4
mode register 4 (PM4). When the P40 to P43 pins are used as an input port, use of an on-chip pull-up resistor can be
specified in 1-bit units by pull-up resistor option register 4 (PU4)
P40/TOOL0
P41/TOOL1
P42
P43
Port 4 is 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 4-8 and 4-9 show the 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, 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).
