Measured error count in 8-bit floating point notation. The content of this register is an
alternative format to the TxtpChkErrCnt.
Mantissa = bits [7:4]
Exponent = bits [3:0]
Error count = (Mantissa/16) x 16
0000 0000 = 0 (decimal)
0101 0111 = (5/16) x 16
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 cur-
rent running error count. Reading the least significant byte latches the upper bytes.
Note: Combined registers 176 to 180,
0000000000 = 0 (decimal)
