MB90670/675 Series
Descriptions for read/write
R/W: Readable and writable
R: Read only
W: Write only
R/W!: Bits for reading operation only or writing operation only are included. Refer to the register lists for specific
resource for detailed information.
Descriptions for initial value
0 : The initial value of this bit is “0”.
1 : The initial value of this bit is “1”.
* : The initial value of this bit is “1” or “0” (decided by levels on pins of MD0 through MD2).
X : The initial value of this bit is indeterminate.
– : This bit is not used. The initial value is indeterminate.
*1: Access prohibited.
*2: This area is the only external access area having an address of 0000FF
H
or lower. An access operation to this
area is handled as that to external I/O area.
*3: The area corresponding to the “(Vacancy)” on the I/O map is reserved, and accessing operation to this area is
handled as that to internal area. No access signal to external devices are generated.
*4: Only bit 15 is writable. Reading bit 10 through bit 15 returns “0” as a reading result.
*5: In the MB90670 series, P81 through P86, P90, P91, PA0 through PA7, PB0 through PB2 are not present. For
this reason, bits corresponding to these pins are not used.
*6: The MB90670 series does not have the I
2
C interface. For this reason, this area is “(Vacancy)” in the MB90670
series.
Note: For bits that is only allowed to program, the initial value set by the reset operation is listed as an initial value.
Note that the values are different from reading results.
For LPMCR/CKSCR/WDTC, there are cases where initialization is performed or not performed, depending
on the types of the reset. However initial value for resets that initializes the value are listed.
