Software Reset
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 preserved.
Figure 1.14 shows the processor mode register 0 and 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: 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.
Reserved bit
Must always be set to “0”
