25.18.18 SMC Pulse Register
Name:
Address:
Access:
Reset:
• NWE_PULSE: NWE Pulse Length
The NWE signal pulse length is defined as:
NWE pulse length = (256 * NWE_PULSE[6]+NWE_PULSE[5:0]) clock cycles.
The NWE pulse must be at least one clock cycle.
• NCS_WR_PULSE: NCS Pulse Length in WRITE Access
In Write access, The NCS signal pulse length is defined as:
NCS pulse length = (256 * NCS_WR_PULSE[6] + NCS_WR_PULSE[5:0]) clock cycles.
the NCS pulse must be at least one clock cycle.
• NRD_PULSE: NRD Pulse Length
The NRD signal pulse length is defined as:
NRD pulse length = (256 * NRD_PULSE[6] + NRD_PULSE[5:0]) clock cycles.
The NRD pulse width must be as least 1 clock cycle.
• NCS_RD_PULSE: NCS Pulse Length in READ Access
In READ mode, The NCS signal pulse length is defined as:
NCS pulse length = (256 * NCS_RD_PULSE[6] + NCS_RD_PULSE[5:0]) clock cycles.
