Bit 00
Verify. If this bit is set to 1, the module will compare its current
programming with the programming downloaded in the BTW. If
they are the same, it will verify good; if they are different, the
module will verify bad. In no case will any programming data in
the BTW be applied to the module.
Bit 01 Temperature scale. 0 = Celsius, 1 = Fahrenheit
Bit 02
BCD select. 1 = all values in BCD format.
0 = all values in 2's complement binary
