Sample C code to convert gray counts to binary:
i
{
int ish;
unsigned long ans,idiv;
ish=1; This is the more complicated direction: In hierarchical stages, starting with a one-bit
right shift, cause each bit to be XORed with all more significant bits.
Ans=gray;
for (;;)
}

{
ans ^= (idiv=ans >> ish);
if (idiv <= 1 || ish == 16) return ans;

Kchar error gray count. The number of words received from the PHY, where one or more control
character errors have been detected. A value of 255 indicates an error count of 255 or more as
this counter does not wrap around to 0. The count value is updated with its current value each
time the Status1 register is read. The count is represented in gray code.
PHY internal error gray count. The number of words received from the PHY, where one or more
internal errors have been detected. A value of 255 indicates an error count of 255 or more as
this counter does not wrap around to 0. The count value is updated with its current value each
time the Status1 register is read. The count is represented in gray code.
Code error gray count: The number of words received from the PHY, where one or more code
errors have been detected. A value of 255 indicates an error count of 255 or more as this
counter does not wrap around to 0. The count value is updated with its current value each time
the Status1 register is read. The count is represented in gray code.
Disparity error gray count. The number of words received from the PHY, where one or more
disparity errors have been detected. A value of 255 indicates an error count of 255 or more as
this counter does not wrap around to 0. The count value is updated with its current value each
time the Status1 register is read. The count is represented in gray code.
