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.Table 2.2.4.1(a) List of shared terminal settings (Rxx)

Terminal	Terminal status				Special output
name	at initial reset	FOUT	TOUT	BZ	XBZ	HFO	HDO	XRMUTE	XTMUTE
R00	R00 (HIGH output)				XBZ
R01	R01 (HIGH output)			BZ
R02	R02 (HIGH output)		TOUT
R03	R03 (HIGH output)	FOUT
R10	R10 (HIGH output)								XTMUTE
R11	R11 (HIGH output)							XRMUTE
R12	R12 (HIGH output)						HDO
R13	R13 (HIGH output)					HFO
R20–R23	R20–R23 (HIGH output)

∗1 When "with pull-up" is selected by mask option (high impedance when "gate direct" is selected)

∗2 The P10–P13 I/O terminals are used for serial I/F (1) and the P30–P33 I/O terminals are for serial I/F (2).

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.
