Table 8
Extended Superframe Structure
The CRC6 checking algorithm is enabled via bit MODE.CRC. If not enabled, all check bits in the
transmit direction are set to ‘1’.
Additions: CRC6 Inversion
Remote alarm is indicated by the periodical pattern ‘1111 1111 0000 0000 …’ in the DL bits.
All signaling schemes are applicable for this multiframing structure. For external access to the DL
bits, refer to section General.

If enabled via bit GCR.CRCI, all CRC bits of one outgoing extended multiframe are
inverted in case a CRC error is flagged for the previous received multiframe.
CRC Alarm Interrupt
As an extension of the alarm interrupt capabilities, the occurrence of a CRC error can
be defined as interrupt source (XC1.MCA) for triggering interrupt port AINT.
