Bits 29:24 – NCS RD SETUP[5:0] NCS Setup Length in READ Access
In read access, the NCS signal setup length is defined as:
NCS setup length = (128* NCS RD SETUP[5] + NCS RD SETUP[4:0]) clock cycles
Bits 21:16 – NRD SETUP[5:0] NRD Setup Length
The NRD signal setup length is defined in clock cycles as:
NRD setup length = (128* NRD SETUP[5] + NRD SETUP[4:0]) clock cycles
Bits 13:8 – NCS WR SETUP[5:0] NCS Setup Length in WRITE Address
In write access, the NCS signal setup length is defined as:
NCS setup length = (128* NCS WR SETUP[5] + NCS WR SETUP[4:0]) clock cycles
Bits 5:0 – NWE SETUP[5:0] NWE Setup Length
The NWE signal setup length is defined as:
NWE setup length = (128* NWE SETUP[5] + NWE SETUP[4:0]) clock cycles
