This bit is used to select the burst read/ write latency between 3
clocks and 7 clocks. BRWL (burst read write latency) bits specify the
access latency in the burst read/ write transfer for the initial access.
Note that these bits are valid only for the synchronous read/ write
operation.
000b = Reserved
001b = Reserved
010b = Reserved
011b = 3 CLK
100b = 4 CLK
101b = 5 CLK
110b = 6 CLK
111b = 7 CLK
Burst Length
These bits are used to select the burst length among 4-burst, 8-
burst, 16-burst, 32-burst, 1024-burst and continuous-burst. Note that
BL (burst length) bits are valid only for the synchronous read/ write
operation.
000b = Continuous-Burst
001b = 4-Burst
010b = 8-Burst
011b = 16-Burst
100b = 32-Burst
101b = 1024-Burst
110b = Reserved
111b = Reserved
Reserved
High Frequency
This bit is used to enable or disable the high frequency mode. High
frequency (HF) bit must be set when the OneNAND clock frequency
is more than 66MHz.
0b = High Frequency Disable (66MHz and under)
1b = High Frequency Enable (Over 66MHz)
Write Mode
This bit is used to select the OneNAND write mode between
synchronous and asynchronous modes.
0b = Asynchronous Write
1b = Synchronous Write
Reserved
