• Description: Synchronous Clock for SETS
• Manufacturer: ETC2 [List of Unclassifed Manufacturers]

Processor Interface Descriptions
The STC4130 supports four common microprocessor control interfaces: SPI, Motorola, Intel, and multiplex
parallel. The control interface mode is selected with the Bus_Mode(0/1) pins:
The following sections describe each bus mode’s interface timing:
SPI Bus Mode
The SPI interface bus mode uses the BUS_CS, BUS_ALE, BUS_WRB, and BUS_RDY pins, corresponding to
CS, SCLK, SDI, and SDO respectively, with timing as shown in figures 9 and 10:
