Reset Select. Determines the action of RST. If
HIGH, a RST command will set the DAC regis-
ters to mid-scale. If LOW, a RST command will
set the DAC registers to zero.
Reset, Edge-Triggered. Depending on the state
of RSTSEL, the DAC Input and Output registers
are set to either mid-scale or zero.
DAC Output Registers Load Control. Rising edge
triggered.
Enabled by the CS, controls data read and write
from the input register.
Enabled by the CS, in combination with A0
selects the Individual DAC Input Registers.
Enabled by the CS, in combination with A1
selects the individual DAC input registers.
Chip Select, Active LOW.
