TX_CHAN_ACTIVE_n
This one bit field indicates the active status of the channel. This field is only
valid if IDLE_CFG for the associated channel is not equal to “00”b (disabled).
If IDLE_CFG is equal to “10” (Automatic, CAS) or “11” (Automatic, Pattern)
then this field is read only and is updated by the AAL1gator. If IDLE_CFG
equals “01” (processor) then the processor activates and deactivates
channels by writing this bit. On read/write:
0) Inactive
1) Active
NOTE: Channels within a 16 bit word should not mix automatic detection
with processor IDLE_CFG modes because there can be contention in
updating these fields.
