what is relation between hard coded mode and serdes1 reference clock?

[zheng]

From the thread LS1043A: Hard Coded RCW  we know if want to make ls1043a enter hard coded mode, the Serdes1 reference clock should be configured at 100MHz. 

what is relation between hard coded mode and serdes1 reference clock?

If my board does't use serdes and no serdes reference clock, can the ls1043 enter the harde coded mode?

Hello leon zheng,

Please refer to the section "4.4.6.3 RCW settings for hard-coded Options" in LS1043 Reference Manual.

Please refer to SerDes PLL and protocol configuration when configuring RCW as hard-coded RCW.

Thanks,

Yiping
