(2) Slave Address Comparison (7 bits)
Slave address comparison is the same as for D/A converter (12-channel) operation (see “1. (2) “Slave Address
Comparison”), with the exception that the CS2 setting determines the number of D/A converter channels and
the number of I/O expander bits.
CS2
D/A converter
When CS2 = “1” is selected, the upper 4 bits (D

to D

) of write operations (I

C bus to parallel interface) are
ignored, and the upper 4 bits or read operations (parallel interface to I
2
C bus) are output at “0” (low).
