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

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.
The higher-order address becomes 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
Must always be set to “0”
0
Note 1: Set bit 1 of the protect register (address 000A16) to “1” when writing new values to this register.
Note 2: Be sure to set this bit to 0 except products whose RAM size and ROM size exceed 15K bytes
and 192K bytes respectively.
In using M30624MG/FG, a product having a RAM of more than 15K bytes and a ROM of more
than 192K bytes, set this bit to 1 at the beginning of user program.
Specify D000016 or a subsequent address, which becomes an internal ROM area if PM13 is set
to “0” at the time reset is revoked, for the reset vector table of user program.
Note 3: With the processor running in memory expansion mode or in microprocessor mode, setting this
bit provides the means of expanding the external memory area. (Normal mode: up to 1M byte,
expansion mode 1: up to 1.2 M bytes, expansion mode 2: up to 4M bytes)
For details, see “Memory space expansion functions”.

0: The same internal reserved
area as that of M16C/60 and
M16C/61 group
1: Expands the internal RAM area
and internal ROM area to 23 K
bytes and to 256K bytes
respectively. (Note 2)
