MSM7583
DEN, EXCK, DIN, DOUT
Serial control ports for the microprocessor interface.
The MSM7583 contains a 6-byte control register. An external CPU uses these pins to read data
, , fromandwritedatatothecontrolregister. DENisthe"Enable"signalinputpin. EXCKisa
data shift clock pulse input pin. DIN is an address and data input pin. DOUT is a data output
pin. Figure 5 shows an input/output timing diagram.
