CONFIGMEMLD Register
Accessing the CONFIGMEMLD Register loads and sequences through the channel
configuration memory.
Address:
Base a 1B (hex)
Type:
Write-only
Word Size:
8-bit
Bit Map:
Not applicable, no bits used.
Strobe Effect:
Read and apply a channel configuration value to the analog input section.
Accessing the CONFIGMEMLD Register loads the channel configuration memory values and
applies the first channel configuration value to the analog input circuitry. After the final write to
the channel configuration memory, accessing the CONFIGMEMLD Register loads the first
channel configuration value. Writing to the CONFIGMEMLD Register again loads the second
channel configuration value, and so on.
Strobing the DAQ Clear Register resets the channel configuration memory to the first value, but
does not load the value. This does not clear the memory of any values written to it prior to the
DAQ Clear strobe. After strobing the DAQ Clear Register, the CONFIGMEMLD Register
should be strobed to load the first value. A scanned data acquisition can be initiated from any
location in the channel configuration memory by using this method.
