(7) Lock-Bit Reading

Command

222 Amended

This command is used to read the value of the lock bit in

flash memory.

Writing H'71 in the first command cycle and reading from

the specifying block address (BA) in the second command

cycle returns the value of the lock bit. If a word instruction

is used for reading, the value of the lock bit will be reflected

in bits 6 and 14 of the read-out word. If a byte instruction is

used, the value of the lock bit will be reflected in bit 6.

Execute the lock-bit reading command in EW0 mode.
