8.2.31 64KB Block Erase with 4-Byte Address (DCh)
The 64KB Block Erase with 4-Byte Address instruction is similar to the 64KB Block Erase instruction
except that it requires 32-bit address instead of 24-bit address. No matter the device is operating in 3-Byte
Address Mode or 4-byte Address Mode, the 64KB Block Erase with 4-Byte Address instruction will always
require 32-bit address to access the entire 256Mb memory.
