• Manufacturer: Oki Semiconductor

Note:
Since reading is made in synchronization with the SYNC signal (8 kHz) if the following control registers are set
For how to set the following control registers, see the method of accessing and controlling the internal data memory.
during operation, maintain the condition for 250 μs or more.

Some registers have different addresses depending on whether access is made via a parallel bus interface or a serial
control interface. Such registers are given an address for serial control interface access immediately below in
parentheses “( )”.
Description of Control Registers
The control registers are described from the next page. Since the control registers mounted on the DSP_A side and
DSP_B side are functionally identical, the register description is given as a common explanation of the DSP_A side
and DSP_B side.
