SerData
Serial Data—This bit is the data for the onboard serial
devices—the calibration EEPROM and the serial DACs.
This bit should be set to the desired value prior to the
active write to the SerClk bit.
0
SerClk
Serial Clock—This bit is the clock input to the onboard
serial device. In order to write to these devices, this bit
should be set first to 0 and then to 1. The data in the
SerData bit will be written to the devices on the
low-to-high transition of the serial clock.
