typical usage:
The Receive Status Byte ’RSTA’ contains comprehensive status information about the
last received frame (HDLC/PPP).
The SCC attaches this status byte to the receive data and thus it should be read from
the RFIFO.
In HDLC/PPP modes the RSTA value can optionally be read from this register address.
In extended transparent mode this status field does not apply.
