Transparent mode Flag; these bits are only used in the transparent mode A
and constitute the fill code for flag stuffing and for flag filtering. These bits
must be set to ‘0’ if subchanneling is used in transparent mode A. Bit No. 15
is the first bit of the flag to be received/transmitted.
No Short Frame suppression; NSF = 1 is only allowed in combination with
HDLC mode and CS = 1.
In this mode the MUNICH32 transfers all data to the shared memory even if
only one byte (or more) per ‘frame’ is received. No short frame interrupt and
no short frame status bit will be generated in this case.
Note:CRC is still calculated and checked and e.g. a frame of 1 or 2 byte length
(in CRC16 mode) will always cause an FI + ERR interrupt.
