Prior to smoke calibration, the user must program the
functional options and parametric selections. This
requires that 14 bits, representing selected values, be
clocked in serially using TEST as a data input and
FEED as a clock input, and then be stored in the
internal EEPROM.
The detailed steps are as follows:
