(5) Additional explanation
• F0H, AAH, 55H, A0H, 80H, 10H, 30H: Command data. Write data in units of bytes.
• RA: Read address
RD: Read data output
• PA: Program address
PD: Program data input
• BA: Block address (BA0~BA6)
• BPA: Verify Block Protect
address
• BD: Block Protect data
Write data to addresses which are divisible by 4 in
units of long word
Please refer to part 8), entitled
Verify Block Protect,
on page 58 of Section 3.4.1 (3),
Basic operation.
If the block is protected, the data 0x0000_0001
will be returned; if it is not protected, the data
0x0000_0000 will be returned.
Please refer to Table 4.4., Block Erase addresses.
