4.2.5 Port 4
using port mode register 4 (PM4). When the P40 to P47 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)
using port input mode register 4 (PIM4).
port output mode register 4 (POM4).
clock output, and timer I/O.
Port 4 is an 8-bit I/O port with a output latch. Port 4 can be set to the input mode or output mode in 1-bit units
Input to the P43 and P44 pins can be specified through a normal input buffer or a TTL input buffer in 1-bit units
Output from the P43 and P45 pins can be specified as N-ch open-drain output (V
This port can also be used for serial interface data I/O, clock I/O, flash memory programmer/debugger data I/O,
Reset signal generation sets port 4 to input mode.
Figures 4-14 to 4-20 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.
Cautions 1. When a tool is connected, the P40 pin cannot be used as a port pin.
3. To use P42/TI04/TO04 as a general-purpose port, set bit 4 (TO04) of timer output register 0
2. To use P43/SCK01, P44/SI01 or P45/SO01 as a general-purpose port, note the serial array unit
When the on-chip debug function is used, P41 pin can be used as follows by the mode setting
on the debugger.
(TO0) and bit 4 (TOE04) of timer output enable register 0 (TOE0) to “0”, which is the same as
their default status setting.
0 setting. For details, refer to Table 12-6 Relationship Between Register Settings and Pins
(Channel 1 of Unit 0: CSI01, UART0 reception).
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).
