Clear To Send Status Change
Indicates that a state transition has occurred on CTS. The actual
state can be read from STAR register (CTS bit).
Transmit Message Repeat
The transmission of the last frame has to be repeated because
– the ESCC2 has received a negative acknowledgement to an
– a collision has occurred after at least one FIFO block of data
– CTS (transmission enable) has been withdrawn after at least
Note: For easier recovery in the case of a collision, XFIFO should
Transmit Pool Ready
A data block of up to 32 bytes can be written to the transmit FIFO.
XPR enables the fastest access to XFIFO. It has to be used for
transmission of long frames, back-to-back frames or frames with
shared flags. However, starting transmission of a new frame
should be initiated after ALLS interrupt instead of XPR

– in bus configurations
– if contents of XFIFO have to be unique, e.g. for automatic

The use of ALLS interrupt is therefore recommended.
XMR or XDU interrupt remains unacknowledged.
