All the Memory FLASH command cycles are write cycles except the 1st cycle of the Read
command and the 4th cycle of the Auto Select command which are read cycles.
The Memory FLASH base address is 0xFF00_0000.
For Write commands the program should poll for RD = WD from RA = WA after the 4th cycle.
For Erase commands the program should poll for RD = 0xFFFFFFFFFFFFFFFF from the
Memory FLASH base address for Chip Erase or SAx for Sector Erase after the 6th cycle.
Symbols:
DID = Device ID, MID = Manufacturer ID, RA = Read Address, RD = Read Data,
SA = Sector Address, WA = Write Address, WD = Write Data
