1.9.5. Read Device Identification Operation (9Fh)

This operation reads the 8-bit device identification of the EPCQ-A 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 22.  EPCQ-A Device Identification
EPCQ-A Device Device ID (Binary Value)
EPCQ4A b'0001 0011
EPCQ16A b'0001 0101
EPCQ32A b'0001 0110
EPCQ64A b'0001 0111
EPCQ128A b'0001 1000

The 8-bit device identification of the EPCQ-A device is shifted out on the DATA1 pin at falling edges of the DCLK signal.
