Description
ADCNST is an extension of ADM32. ADCNST first checks whether the data
field value at the remote address is zero; it then performs different adds and
moves on the result. ADCNST is typically used to extend the counter value of
PWCNT.
min_off
A 25-bit constant value that is added to the data field value if the
remote data field is null.
data
A 25-bit value that is always added to the remote data field.
Default: 0.
hr_data
Seven least significant bits of the data addition to the remote data
field.
Default: 0.
