D7
Measured error count in 8-bit floating point notation. The contents of this register are an
alternative format to the RxtpChkErrCnt.
Mantissa = bits [7:4]
Exponent = bits [3:0]
Error count = (Mantissa/16) x 16
0000 0000 = 0 (decimal)
1111 1111 = (15/16) x 16
D38
D6
When using a defined timebase, this register holds the error count from the last
completed timebase. In the continuous timebase setting, the register holds the
current running error count. Reading the least significant byte latches the upper
bytes.
Note: Combined registers 48 to 52,
0000000000 = 0 (decimal)
