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 (Note4)

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 0316. (PM00 and PM01 both are set to “1”.)
Note 3: Valid in microprocessor and memory expansion modes.
Note 4: If the entire space is of multiplexed bus in memory expansion mode, choose an 8-
bit width.The processor operates using the separate bus after reset is revoked, so the entire
space multiplexed bus cannot be chosen in microprocessor mode.
P31 to P37 become a port if the entire space multiplexed bus is chosen, so only 256 bytes can
be used in each chip select.

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

Note 1: Set bit 1 of the protect register (address 000A16) to “1” when writing new values to this register.
Note 2: When the reset is revoked, this bit is set to “0”. To expand the internal area, set this bit to “1”
in user program. And the top of user program must be allocated to D000016 or subsequent
address.

Wait bit
0 : No wait state

0: The internal RAM area is 15 kbytes
or less and the internal ROM area is

1: Expands the internal RAM area
and internal ROM area to over 15
kbytes and to over 192 kbytes
respectively. (Note 2)
