lc89051v Sanyo Semiconductor Corporation, lc89051v Datasheet - Page 12

• Manufacturer Part Number: lc89051v
• Description: Digital Audio Interface Receiver
• Manufacturer: Sanyo Semiconductor Corporation

Microcontroller 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 setting:
• System stop
• Data input pin setting
• 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.
