Data Sheet
17.5.1
17.5.1.1 RFIFO - Receive FIFO
RFIFO
A read access to any address within the range 00h-1Fh gives access to the “current”
FIFO location selected by an internal pointer which is automatically incremented after
each read access. This allows for the use of efficient “move string” type commands by
the microcontroller.
The RFIFO contains up to 64 bytes of received data.
After an ISTAH.RPF interrupt, a complete data block is available. The block size can be
4, 8, 16, 32 bytes depending on the EXMR.RFBS setting.
After an ISTAH.RME interrupt, the number of received bytes can be obtained by reading
the RBCL/RBCH registers.
17.5.1.2 XFIFO - Transmit FIFO
XFIFO
A write access to any address within the range 00-1F
location selected by an internal pointer which is automatically incremented after each
write access. This allows the use of efficient “move string” type commands by the
microcontroller.
Depending on EXMR.XFBS up to 16 bytes of transmit data can be written to the XFIFO
following an ISTAH.XPR interrupt.
17.5.1.3 ISTAH - Interrupt Status Register HDLC
