Microprocessor Interface (SCLK/CL, XLAT/CE, SWDT/DI, SRDT/DO, DQSY/LD)
1. Data input and output addresses are allocated as follows:
2. The input command codes control the following settings:
System stop
Data input pin settings
Input bi-phase data output selection
Validity flag output selection
Audio data output format setting
DI1: Stops VCO operation and thus stops the system.
DI2: Selects which input data to demodulate.
DI3 and DI4: Select the E/DOUT pin output.
DI5 and DI6: Set the audio data output format.
All bits are set low immediately after XMODE is switched from low to high. DI0 and DI7 are not used.
No. 5237-12/16
