void digOutConfig(unsigned int outputMode);
Each of the BL2100 high-current outputs (OUT00–OUT15) has the capability of being configured in
software as either sinking or sourcing using the digOutConfig function. Execute digOutConfig
at the start of your application to initially set OUT00–OUT15 to be OFF for the type of circuit that you
have, either sinking or sourcing.
To properly set the high-current outputs, you will need to decide for each channel whether the output is
sinking or sourcing. The digOutConfig function will then ensure that each output remains OFF when
the digital output control interface is
until you activate the desired output driver(s)/channel(s) using digOut.
outputMode is a 16-bit parameter where each bit corresponds to one of the following high-current
outputs.
The high-current outputs can be configured to be sinking or sourcing outputs by setting the correspond-
ing bit to an 0 or 1: 0 = sinking, 1 = sourcing.
