MPC555 burst access

HI,

On my board, there is a MPC555 connected to two AM29BL162 (Burst Flash). Using the AMD application note (Utilizing the Burst Mode Flash in a Motorola MPC555 System) for the register configuration, I saw that the instruction fetch is still in normal transfert.

Can someone tell me all the register to set for enabling burst Mode ?
I configured the
  • BRx & ORx
  • BBCR

What did I miss ?

Hoping someone can help
