Bit Field Description Init Access
31:28 Reserved – 0 RO
27:16 Auto_dec_sel_vec The auto-sense mapping result. Each bit indicates the
detection of a flash device. The bit definition is:
[11] auto_det_sst25_4m
[10] auto_det_sst25_2m
[9] auto_det_sst25_1m
[8] auto_det_saifun_4m (BCM5754 and BCM5754M only)
Reserved (other devices)
[7] auto_det_saifun_2m (BCM5754 and BCM5754M only)
Reserved (other devices)
[6] auto_det_saifun_1m (BCM5754 and BCM5754M only)
Reserved (other devices)
[5] auto_det_st_4m
[4] auto_det_st_2m
[3] auto_det_st_1m
[2] auto_det_at_4m
[1] auto_det_at_2m
[0] auto_det_at_1m
0RO
15 Reserved – 0 RO
7:4 Auto_config_en_pulse_cnt The kickoff time of auto-sense FSM. This counter will not be
reset. It is mainly used for FPGA debug. It increments once
whenever a POR kicks off auto-sense FSM.
Random RO
3:1 Auto_conf_state The auto-sense FSM state
• 001 = Auto Config AT45
• 010 = Auto Config STM45
• 011 = Auto Config Saifun
• 100 = Auto Config SST25
0RO
0 Auto_config_busy
• 1 = Auto-config FSM is busy
• 0 = Auto-config is complete
0RO
