Preliminary Product Specification
The ext_vcm_bc register controls the driving strength in the buffer supplying the voltage on the VCM pin. If this pin is not
in use, the buffer can be switched off. If current is drawn from the VCM pin, the driving strength can be increased to keep
the voltage on this pin at the correct level.
