Hello,

I'm MJ (Korean)

I'm working on development RF system using AFE7444 chip.

In AFE7444 Programmer Guide document 'Start-Up E-Fuse Shift' section,

The document said read register C2 in Traffic Controller page.(Poll for E-fuse loading done.)

But in 'Register Set' document doesn't have C2 register in Traffic Controller page.

Furthermore, not only C2 but some more register is not documented in 'Register Set'

So I wonder that my document is up to dated document or not.

Below is my document information.

Programmers Guide : SLAU793A , May 2019 - Revised September 2019

Register SET : SLAU798, September 2019

Thanks for your help.

Hi Yeonyeol,

The document that you have is up to date. To bringup the AFE there are some registers used that are not mentioned in the register map. We suggest following the Programmer's Guide document for the proper way to set these registers.
