CHAPTER 2: POWER SUPPLY AND INITIAL RESET
If an instruction which does not permit extended operation is used as the following instruction, the
operation is not guaranteed. Therefore, do not write data to the EXT register for initialization only.
Refer to the "S1C63000 Core CPU Manual" for extended addressing and usable instructions.

2.2.3 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 2.2.3.1 shows the list of the shared terminal settings.
