Format diagram for read/write timing
When /CS=1, the SO output becomes high-impedance.
* Be sure to set /CSB to “1” when making an access to the control register.
The sound field processing program used for Sub DSP is down-loaded by using the /CSB, SCK, and SI terminals.
Please refer to Application manual for the details of Sub DSP.
4. External Interface
RAMA0-16, RAMD0-7, RAMCEN, RAMOEN, RAMWEN
An external SRAM can be connected to Sub DSP.
5. General purpose I/O ports
OPORT0-7, IPORT0-7
OPORT0-7 terminals are output ports for general purpose. Data written on the register (address 0x04) are outputted
from these terminals.
IPORT0-7 terminals are input ports for general purpose. Data inputted to these terminals can be read from the
register (address 0x05).
6. Initial clear
/IC
This LSI requires initial clear when turning on the power.
7. LSI test terminals
TEST
Leave the test terminals open in normal use.
