¡ Semiconductor
DENC, EXCKC, DINC, DOUTC
Serial control ports for MCU interface.
Reading and writing data are performed by an external MCU through these pins. The 8-byte
control registers (CRC0 - 7) are provided for the CODEC unit in this device. DENC is the "Enable"
control signal input, EXCKC is the data shift clock input, DINC is the address and data input, and
DOUTC is the data output. Figure 8 shows input/output timing diagram.
The register map is shown below.
