Read Device Identification Operation (9Eh or 9Fh)

This operation reads the 8-bit device identification of the EPCQ-L device from the DATA1 output pin. If this operation is shifted in while an erase or write cycle is in progress, the operation is not executed and does not affect the erase or write cycle in progress.

Table 25.  EPCQ-L Device Identification
EPCQ-L Device Silicon ID (Binary Value)
EPCQ-L256 b'0001 1001
EPCQ-L512 b'0010 0000
EPCQ-L1024 b'0010 0001

The 8-bit device identification of the EPCQ-L device is shifted out on the DATA1 pin on the falling edge of the DCLK signal. LSB is first shifted into the FPGA device.
