Every sector is further divided into 16 subsectors with 4 KB of memory. Therefore, there are 512 (32 x 16)
subsectors for the EPCQ16 device, 1,024 (64 x 16) subsectors for the EPCQ32 device, 2,048 (128 x 16) subsectors
for the EPCQ64 device, 4,096 (256 x 16) subsectors for the EPCQ128 device, 8,192 (512 x 16) subsectors for
the EPCQ256 device, and 16,384 (1,024 x 16) subsectors for the EPCQ512 device.
