Transmit FIFO (XFIFO)
Interrupt Status Register (ISTA_A/B)
Mask Register (MASK_A/B)
Transmit Data 7…0, data byte to be transmitted on the serial interface.
Interrupt controlled data transfer.
Up to 32 bytes of transmit data can be written to the XFIFO following an
XPR-interrupt.
Receive Message End.
A message of up to 32 bytes or the last part of a message greater then
32 bytes has been received and is now available in the RFIFO. The
message is complete! The actual message length can be determined by
reading the registers RBCL, RBCH. RME is not generated when an
extended HDLC- frame is recognized in auto-mode (EHC interrupt).
Receive Pool Full.
A data block of 32 bytes is stored in the RFIFO. The message is not yet
completed!
Transmit Pool Ready.
A data block of up to 32 bytes can be written to the XFIFO.
