S/Q Channel Change
A change in the received 4-bit S channel (TE or LT-T mode) or Q channel (NT or LT-S
mode) has been detected. The new code can be read from the SQRR. This bit is reset
by a read of the SQRR.
Determines which of the two channels B1 or IC1 is connected to register
C1R and/or B1CR, for monitoring, test-looping and switching data
to/from the processor.
Determines which of the two channels B2 or IC2 is connected to register
C2R and/or B2CR, for monitoring, test-looping and switching data
to/from the processor.
