DS125DF410: About Initiating Aaptation

Part Number: DS125DF410

Hi, team

I have a question about 7.5.20 Initating Adaptation.

It is described that CTLE adaptation can be initiaed by setting and thenclearing register 0x2f,bit 0 in datasheet.

I set in reg 0x2f. but reg 0x2f was not cleared even if I waited for several minutes.

Will initiation take time?

The input order to a reg is as follows.

1. reg 0x2f   0xB6 → 0xB7

2. reg 0x0A 0x18 → 0x1C

3.reg 0x0A  0x1C→ 0x18

I reset CDR.But reg 0x2f did not change.

The ADAPT_mode of this time is adapt CTLE only(reg 0x31 0x20)

Regard.
