CHAPTER 2: POWER SUPPLY AND INITIAL RESET
2.2.4 Terminal settings at initial resetting
The output port (R) terminals and I/O port (P) terminals are shared with special output terminals and
input/output terminals of the serial interface. These functions are selected by the software. At initial
reset, these terminals are set to the general purpose output port terminals and I/O port terminals. Set
them according to the system in the initial routine. In addition, take care of the initial status of output
terminals when designing a system.
Table 2.2.4.1 shows the list of the shared terminal settings.

For setting procedure of the functions, see explanations for each of the peripheral circuits.
2.3 Test Terminal (TEST)
This is the terminal used for the factory inspection of the IC. During normal operation, connect the TEST
terminal to VDD.
