Software Reset
Writing “1” to bit 3 of the processor mode register 0 (address 000416) applies a (software) reset to the
microcomputer. A software reset has almost the same effect as a hardware reset. The contents of internal
RAM are retained.
Processor Mode
(1) Types of Processor Mode
The single-chip mode is supported in processor mode.
Single-chip mode
In single-chip mode, only internal memory space (SFR, internal RAM, and internal ROM) can be accessed.
Ports P0 to P16 can be used as programmable I/O ports or as I/O ports for the internal peripheral functions.
Fig. BG-1 shows the structure of processor mode register 0 and processor mode register 1.

Software reset bit
The device is reset when this bit is set
to “1”. The value of this bit is “0” when
read.
Note 1: Set bit 1 of the protect register (address 000A16) to “1” when writing new
values to this register.

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be
indeterminate.
