The recommended csHoldTime value is 0x03 (RT1020 Reference Manual). But what does a value of 0x03 mean? ist it 3 ns? The waitTimeCfgCommands is specified in 100 us. Is it the same for csHoldTime?


Our used flash specifies CS# Setup and Hold Time of 4 ns. What do I have to set csHoldTime to?


Kind regards,
