Data format

Data will be read out in 2th complement. Normally the upper 4 bit (bit 12..bit 15) will be sign expanded in hardware. With this feature it

is possible to use the read data directly as signed 16 bit integer values.

If the option digital inputs is installed and the register SPC_PATTERNENABLE is set, the digital inputs will be read out in the upper four bits

of the both channels. In this case it is necessary to divide the data in the two analogue and the eight digital channels before processing the

data.

SPC_PATTERNENABLE = 0

SPC_PATTERNENABLE = 1
