If the value in the RxtpChkErrCnt register (register 53) exceeds this target error
count, an interrupt will be generated. The value is represented as an 8-bit floating
point number.
Mantissa = bits[7:4]
Exponent = bits[3:0]
Error count = (Mantissa/16) x 16
0000 0000 = 0 (decimal)
1111 1111 = (15/16) x 16
Note: This register value does not represent a target bit error rate (BER). Rather, it is a target
When using a defined timebase, this register holds the error count from the last com-
pleted timebase. In the continuous timebase setting, the register holds the current
running error count. Reading the least significant byte (LSB) latches the upper bytes.
