CHAPTER 2 PIN FUNCTIONS
(b) TOOL1
This is a clock output pin for a debugger.
When the on-chip debug function is used, P41/TOOL1 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).
Caution The function of the P40/TOOL0 pin varies as described in (a) to (c) below.
In the case of (b) or (c), make the specified connection.
(a) In normal operation mode and when on-chip debugging is disabled (OCDENSET = 0) by an
option byte (000C3H)
=> Use this pin as a port pin (P40).
(b) In normal operation mode and when on-chip debugging is enabled (OCDENSET = 1) by an
option byte (000C3H)
=> Connect this pin to VDD via an external resistor, and always input a high level to the pin
before reset release.
(c) When on-chip debug function is used, or in write mode of flash memory programmer
=> Use this pin as TOOL0.
Directly connect this pin to the on-chip debug emulator or a flash memory programmer,
or pull it up by connecting it to VDD via an external resistor.
2.2.6 P50 to P57
P50 to P57 function as an I/O port. This port can also be used for serial interface data I/O, timer input, and segment
output of LCD controller/driver.

The following operation modes can be specified in 1-bit units.
(1) Port mode
P50 to P57 function as an I/O port. P50 to P57 can be set to input or output port in 1-bit units using port mode
register 5 (PM5). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 5 (PU5).
