Interrupt Status Register (ISTA_A/B)
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).
In DMA-mode a RME-interrupt is generated after the DMA-transfer has been
finished correctly, indicating that the processor should read the registers
RBCH/RBCL to determine the correct message length.
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.
