LOADDAC
The selected DAC register becomes transparent
when LOADDAC is LOW. It is in the latched state
when LOADDAC is HIGH.
21
22
RESET
Asynchronous Reset Input. Sets the DAC register
to either zero-scale (000H) or mid-scale (800H)
when LOW. RESETSEL determines which code is
active.
RESETSEL
When LOW, a LOW on RESET will cause the DAC
register to be set to code 000H. When RESETSEL
is HIGH, a LOW on RESET will set the registers to
code 800H.
23

CS
Chip Select. Active LOW.
R/W
Enabled by CS. Controls data read and write from
the input register.
