In normal functional mode, these bits are zero.
Output Error (Read Only)
This bit is set high when the total number of output channels is programmed to be
more than the maximum capacity of 4096, in which case the output channels beyond
the maximum capacity should be disabled.
This bit will be cleared automatically after programming is corrected.
Input Error (Read Only)
This bit is set high when the total number of input channels is programmed to be more
than the maximum capacity of 4096, in which case the input channels beyond the
maximum capacity should be disabled.This bit will be cleared automatically after pro-
gramming is corrected.
BER Error Flag[n]
If BERF[n] is high, it indicates that BER Receiver Error Register [n] (BRER[n]) is not
zero.
If BERF[n] is low, it indicates that BER Receiver Error Register [n] (BRER[n]) is zero.
