17
RSTSEL
Reset Select. Determines the action of RST. If
HIGH, a RST command will set the DAC registers to
mid-scale. If LOW, a RST command will set the DAC
registers to zero.
18
RST
Reset, Rising Edge Triggered. Depending on the
state of RSTSEL, the DAC registers are set to either
mid-scale or zero.
19
LOADDACS
DAC Output Registers Load Control. Rising edge
triggered.
20
R/W
Enabled by the CS, Controls Data Read and Write
from the Input Registers.
21
A1
Enabled by the CS, in Combination With A0 Selects
the Individual DAC Input Registers.
22
A0
Enabled by the CS, in Combination With A1 Selects
the Individual DAC Input Registers.
