21 APORTYMASTER-
DIS
Determines if the OPAx will request the APORT bus Y with POSSEL, NEGSEL or APORTOUTSEL. This bit allows multiple
APORT connected devices to monitor the same APORT bus simultaneously by allowing the OPAx to not master the selec-
ted bus. When 1, the determination is expected to be from another peripheral, and the OPAx only passively looks at the
bus. When 1, the selection of channel for a selected bus is ignored (the bus is not), and is whatever selection the external
device mastering the bus has configured for the APORT bus.
