No function if standard doubleframe format is enabled (MODE.CRC = 0, ref. to
EMOD.DFSN). If MODE.CRC is set to one, this bit is set in (multiframe) synchronous state
at the beginning of every received CRC multiframe (or every eighth received doubleframe).
It is cleared
– with the first read access to the stack RSN, or
– automatically with beginning of frame 15 of every received CRC multiframe (this is valid
only if EMOD.DFSN = 0). In that case, a read access to the stack and to Si bits should be
avoided. Stack RSN and Si bits RSP.RS13 and RSP.RS15 will be updated with beginning
of every CRC multiframe (or every eighth doubleframe). RSP.RFLG should be monitored
continuously at time intervals less than 2 ms (1.5 ms recommended) to receive correct
Sn/Si-bit information.
If the use of the signaling stacks RSIG and XSIG is enabled by setting bit XC0.ISIG, this flag
is set if access to one of these stacks (2 bytes) is not completed before a new assigned
request occurs. The flag is cleared by setting bit CCR.CLR.
Set by a parity error in any transmit or receive channel. Cleared by bit CCR.CCPY.
The bit will be set during alarm simulation.
If channel parity check is enabled by programming register CPY this bit is set after a transmit
channel parity error occurs in the selected channel. This flag is meaningful only when the
external transmit channel parity input XCHPY is used (enabled by setting bit XC0.EPY). The
flag is set during alarm simulation.
First bit in FAS-word. Used only in doubleframe format, otherwise fixed to ‘1’.
First bit in service word of frame 13. Significant only in CRC-multiframe format, otherwise
fixed to ‘0’. This bit is updated with beginning of every received CRC multiframe (refer to
RSP.RFLG and XSP.MRMB).
First bit in service word of frame 15. Significant only in CRC-multiframe format, otherwise
fixed to ‘0’. This bit is updated with beginning of every received CRC multiframe (refer to
RSP.RFLG and XSP.MRMB).
