MSM7584C
10/57
(Voice Recording Serial Controller)
DIO
Input/output pin that outputs write data and to input read data.
Connect this pin to the DIN pin, DOUT pin of the serial registers and the DOUT pin of the serial
voice ROM. If neither a serial register nor a serial voice ROM is connected, pull this pin up with
an approx. 50 k
W
resistor.
WE
Output that selects the read mode or write mode.
Connect this pin to the
WE
pin of the serial registers.
SAD
Read/write start address output.
Connect this pin to the SAD pin of the serial registers and the SADX pin of the serial voice ROM.
SAS
Output of clocks for writing serial address.
Connect this pin to the
SAS
pin of the serial registers and the
SASX
and
SASY
pins of the serial
voice ROM.
TAS
Strobe signal output that sets the serial address which is entered from the SAD pin, to the address
counter inside the serial register/serial voice ROM.
Connect this pin to the
TAS
pins of the serial registers and serial voice ROM.
RWCK
Output of clocks for reading data from or writing data to the serial registers.
Connect this pin to the
RWCK
pin of the serial registers and the
PDCK
pin of the serial voice ROM.
CS1
,
CS2
Chip select pins.
Connect
CS1
to the
CS
pin of the serial registers.
Connect
CS2
to the
CS
pin of the serial voice ROM.
