Name Function
XMCM Transmit multichannel selection
XMCM = 00b No transmit multichannel selection mode is on. All
channels are enabled and unmasked. No channels can
be disabled or masked.
XMCM = 01b All channels are disabled unless they are selected in the
appropriate transmit channel enable registers (XCERs).
If enabled, a channel in this mode is also unmasked.
The XMCME bit determines whether 32 channels or 128
channels are selectable in XCERs.
XMCM = 10b All channels are enabled, but they are masked unless
they are selected in the appropriate transmit channel
enable registers (XCERs).
The XMCME bit determines whether 32 channels or 128
channels are selectable in XCERs.
XMCM = 11b This mode is used for symmetric transmission and
reception.
All channels are disabled for transmission unless they
are enabled for reception in the appropriate receive
channel enable registers (RCERs). Once enabled, they
are masked unless they are also selected in the
appropriate transmit channel enable registers (XCERs).
The XMCME bit determines whether 32 channels or 128
channels are selectable in RCERs and XCERs.
