Receiver ON: Writing a “1” into this bit location turns on the
Receive Section of channel n. Writing a “0” shuts off the
Receiver Section of channel n.
NOTES:
1.
This bit provides independent turn-off or turn-on
control of each receiver channel.
2.
In Hardware mode all receiver channels are always
on.
