DAQ Clear Register
Accessing the DAQ Clear Register location clears the data acquisition circuitry.
Address: Base a 19 (hex)
Type: Read-only
Word Size: 8-bit
Bit Map: Not applicable, no bits used.
Strobe Effect: Cancels any data acquisition operation in progress, empties the ADC FIFO,
clears the OVERRUN bit in Status Register 1, clears the OVERFLOW bit in
Status Register 1, clears the DAQCOMP bit in Status Register 1, clears any
pending ADC interrupt, and resets the configuration memory to the initial value
(no values are lost).
Note: If the channel configuration memory contains valid information and no new values are
to be added before restarting the data acquisition sequence, the CONFIGMEMLD
Register should be strobed following a DAQ Clear strobe.
