  19 The status register, data, or read device identification is read out at least once and is continuously read out until the nCS pin is driven high. 
 
 
 
  20 The default EPCQ-L dummy clocks are 8 and 10 for the fast read and extended quad input fast read operations, respectively. The  Intel® Quartus® Prime Programmer configures the NVCR automatically during the JIC programming to meet the FPGA dummy clock requirement for configuration. 
 
 
 
  21 A write bytes operation requires at least one data byte. If more than 256 bytes are sent to the device, only the last 256 bytes are written to the memory. 
 
 
 
  22 Erase bulk is applicable to EPCQ-L256 only. 
 
 
 
  23 Erase die is applicable to EPCQ-L512 and EPCQ-L1024 only.
