1.6.3.2. Write Non-Volatile Configuration Register Operation (B1h)
You need to write the non-volatile configuration registers for EPCQ devices for different configuration schemes. If you are using the .jic file, the Intel® Quartus® Prime programmer sets the number of dummy clock cycles and address bytes accordingly. If you are using an external programmer tools, you must set the non-volatile configuration registers.
To set the non-volatile configuration register, follow these steps:
- Execute the write enable operation.
- Execute the write non-volatile configuration register operation.
- Set the 16-bit register value.
Set the 16-bit register value as b'1110 111y xxxx 1111 where y is the address byte (0 for 4-byte addressing and 1 for 3-byte addressing) and xxxx is the dummy clock value. When the xxxx value is from 0001 to 1110, the dummy clock value is from 1 to 14. When xxxx is 0000 or 1111, the dummy clock value is at the default value, which is 8 for standard fast read (AS x1) mode and 10 for extended quad input fast read (AS x4 mode).
