CONFIGMEMLD Register

Accessing the CONFIGMEMLD Register loads and sequences through
the channel configuration memory.

Address:

Base address + 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.
