Bit Field Value Description
15-10 Reserved 0 Reserved bits (not available for your use). They are read-only bits and return 0s when read.
9 XMCME Transmit multichannel partition mode bit. XMCME determines whether only 32 channels or all 128
channels are to be individually selectable. XMCME is only applicable if channels can be individually
disabled/enabled or masked/unmasked for transmission (XMCM is nonzero).
0 2-partition mode. Only partitions A and B are used. You can control up to 32 channels in the
transmit multichannel selection mode selected with the XMCM bits.
If XMCM = 01b or 10b, assign 16 channels to partition A with the XPABLK bits. Assign 16 channels
to partition B with the XPBBLK bits.
If XMCM = 11b(for symmetric transmission and reception), assign 16 channels to receive partition A
with the RPABLK bits. Assign 16 channels to receive partition B with the RPBBLK bits.
You control the channels with the appropriate transmit channel enable registers:
XCERA: Channels in partition A
XCERB: Channels in partition B
1 8-partition mode. All partitions (A through H) are used. You can control up to 128 channels in the
transmit multichannel selection mode selected with the XMCM bits.
You control the channels with the appropriate transmit channel enable registers:
XCERA: Channels 0 through 15
XCERB: Channels 16 through 31
XCERC: Channels 32 through 47
XCERD: Channels 48 through 63
XCERE: Channels 64 through 79
XCERF: Channels 80 through 95
XCERG: Channels 96 through 111
XCERH: Channels 112 through 127
