SB_BASE[1:0]
Serial Bus Base Address
Input
The external microprocessor must apply these two
signals as static signals to the device because they
determine the two LSBs of the serial bus base address.
SCL
SDA
Serial Clock Line
Input
In conjunction with SDA, SCL controls the
microprocessor interface according to the protocol
described in Appendix A.
Serial Data Access
Bidirectional
In conjunction with SCL, SDA controls the
