19.3 Toggle Bit (D6)

read from the same address is reversed bit 6 (D6) of the data (toggling between 0 and 1) until the operation is com-
pleted. Therefore, this toggle bit provides a software mechanism to check the completion of each operation. Usually
perform read operations repeatedly for data polling until the same data is read twice from the same address in the
flash memory. After the byte program, chip erase, or read protect command sequence is executed, the initial read of
the toggle bit always produces a "1".
After the byte program, chip erase, and read protect command sequence is executed, any consecutive attempts to
be executed until this operation is completed. To check the completion of the read protect operation, perform
read operations repeatedly for data polling until the same data is read twice from the same address in the flash
memory. During the read protect operation, any attempts to read from the same address is reversed bit 6 of the
data (toggling between 0 and 1).
It takes a maximum of 40 µs to set read protection in the flash memory. The next command sequence cannot
