Pin circuit
Data bus
17 to 24
D0 to D7
The bus width can be set to be either 8 bits or 16bits by the BUSWD
I/O
pin (pin 48).
For data input, only the lower 8 bits (D0 to D7) are valid.
25 to 32
D8 to D15
Data bus (in 16-bit mode)
Output
These pins are held in the output off state when BUSWD is low.

Notes: 1. This pin must be connected to VDDD or VSSD if the IC is used in serial interface mode (when SP is high).
2. A capacitor of at least 2000pF must be inserted between VDDD and VSSD.
Control Registers
This IC includes both registers that can be read and registers that can be written. These registers can be accessed using
either the serial interface (CCB) or the parallel interface. The SP pin switches between these interfaces.
The initial values of the write registers are the data loaded into internal registers when a reset signal (RST) is received.
These values are recommended values that do not need to be changed during normal operation.
If the parallel interface is used, applications must hold the address fixed at 00H when reading out data to which error
correction has been applied. If the CCB interface is used, the application needs only to specify the CCB address (#FB).
The address 00H is an invalid address for writing.
The addresses other than those specified below are control addresses particular to the IC. Applications must not specify
those addresses.
