7. ASMI Erase & Write Start IDLE inp_vld= 1 BUS_RQST ack= 1 busy = 0 NEW_ADDR no yes ERASE busy = 1 ERASE_BUSY busy = 0 WRITE_PAGE end_of_page OR pkg_ended PAGE_DONE yes no package ended new sector WAIT_BUSY busy = 0 NEW_PAGE SSM & Parameter Path • Active Serial Memory Interface • 64 sectors • 2 Mb/ sector • Sector must be erased before writing • 256 bytes can be written / operation

8. ASMI Read Start IDLE read param pulse READ_RQST ack= 1 busy = 0 READ_PAGE second last word LAST_WORD Parameter&ConfigurationUpdate • Infinite bytes can be read / operation

9. Parameter update through FESA Parameter&ConfigurationUpdate • Write the parameters in the flash • dabinit process with an rbf file • Send two commands • Update BLEPM Param Flash • Refresh BLEPM Param Table
