In standard read access, the NCS signal pulse length is defined as:
The NCS pulse length must be at least one clock cycle.
In page mode read access, the NCSRDPULSE field defines the duration of the first access to one page.
In standard read access, the NRD signal pulse length is defined in clock cycles as:
The NRD pulse length must be at least one clock cycle.
In page mode read access, the NRDPULSE field defines the duration of the subsequent accesses in the page.
In write access, the NCS signal pulse length is defined as:
The NCS pulse length must be at least one clock cycle.
The NWE signal pulse length is defined as:
The NWE pulse length must be at least one clock cycle.
