ISTAD
RME ... Receive Message End
One complete frame of length less than or equal to 32 bytes, or the last part of a frame
of length greater than 32 bytes has been received. The contents are available in the
RFIFOD. The message length and additional information may be obtained from RBCHD
and RBCLD and the RSTAD register.
RPF ... Receive Pool Full
A 32-byte block of a frame longer than 32 bytes has been received and is available in
the RFIFOD. The frame is not yet complete.
RSC ... Receive Status Change. Used in auto mode only
A status change in the receiver of the remote station - Receiver Ready/Receiver Not
Ready - has been detected (RR or RNR S-frame). The actual status of the remote station
can be read from the STARD register (RRNR bit).
XPR ... Transmit Pool Ready
A data block of up to 32 bytes can be written to the XFIFOD.
An XPR interrupt will be generated in the following cases:
• after an XTF or XIF command, when one transmit pool is emptied and the frame is not
• after an XTF together with an XME command is issued, when the whole transparent
• after an XIF together with an XME command is issued, when the whole I frame has
TIN ... Timer Interrupt
The internal timer and repeat counter has expired (see TIMR1 register).
CIC ... C/I Channel Change
A change in C/I channel 0 or C/I channel 1 (only TE mode) has been recognized. The
