Description
Modifies the value of the
ppm delta tolerance from
channel register 0x64
00 - ppm_delta[7:0] =1 x
ppm_delta[7:0]
01 - ppm_delta[7:0] =1 x
ppm_delta[7:0] +
ppm_delta[3:1]
10 - ppm_delta[7:0] =2 x
ppm_delta[7:0]
11 - ppm_delta[7:0] =2 x
ppm_delta[7:0] +

Get ppm error from
ppm_count - clears when
done. Normally updates
continuously, but can be
manually triggered with read
value from channel register
0x3B and 0x3C
Determines max tap limit for
DFE tap 1
