Description
Obtains the maximum number of channels that may be activated simultaneously in the specified sub-unit.
Remarks
A single-channel multiplexer (MUX type) allows only one channel to be closed at any time. In some other models such as high-density matrix types a limit is imposed to prevent overheating; although it is possible to disable the limit for these types (see pipx40_setDriverMode), doing so is not recommended.
