DEN , EXCK, DIN, DOUT
Serial control ports for the microprocessor interface.
The MSM7582 and MSM7582B contain a 6-byte control register. An external CPU uses these pins
to read data from and write data to the control register. DEN is an enable signal input pin. EXCK
is a 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.
