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 a configuration of 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.
PM04
0 0 : Multiplexed bus is not used
0 1 : Allocated to CS2 space
1 0 : Allocated to CS1 space
1 1 : Allocated to entire space (Note 4)

select bit (Note 3)
0 : Address output
1 : Port function
(Address is not output)
BCLK output disable bit
0 : BCLK is output
1 : BCLK is not output
(Pin is left floating)
Note 1: Set bit 1 of the protect register (address 000A16) to “1” when writing new values to
this register.
Note 2: If the VCC voltage is applied to the CNVSS, the value of this register when reset is
03 16. (PM00 and PM01 are both set to “1”.)
Note 3: Valid in microprocessor and memory expansion modes.
Note 4: In microprocessor mode, multiplexed bus for the entire space cannot be selected.
In memory expansion mode, when multiplexed bus for the entire space is selected,
address bus range is 256 bytes in each chip select.

Nothing is assigned.
These bits can neither be set nor reset. When read, their contents are
indeterminate.

Note: Set bit 1 of the protect register (address 000A16) to “1” when writing new values to
this register.
