R/W
Enabled by CS, Controls Data Read from and Write
to the Input Registers.
21
LOADDACS
DAC Output Registers Load Control. Rising edge
triggered. Transfers Data from the Input Registers to
the DAC Registers, Updating the DAC Output.
22
RST
Reset, Rising Edge Triggered. DAC7642 resets to
mid-scale, DAC7643 resets to zero. (Resets Both
Input Registers and DAC Registers)
23
DACSEL
Enabled by CS. Selects the individual DAC Input
Registers. (LOW Selects Register A, HIGH Selects
Register B)
