of the 6th bit (D6) in data read by a read operation is reversed each time a read is performed. This bit reversal can be
used as a software mechanism for checking the completion of each operation. Normally, perform read operations twice
on the same address in the flash memory, and perform polling until the same data is read from the flash memory.
bit read by the first read operation is always "1".
Note 1: If FLSCR1<FLSMD> is set to "disable", the toggle bit is not reversed.
Note 2: Do not read the toggle bit by using a 16-bit transfer instruction. If the toggle bit is read using a 16-bit transfer
Note 3: Because the instruction cycle is longer than the write time in SLOW mode, the value is not reversed, even if the

enabled or disabled, read 0xFF7F in product ID mode. Refer to Table 21-4 for further details. The time needed
to enable or disable the security program is 40 μs maximum. The next command sequence cannot be executed
until the security program setting is completed. To check the completion of the security program setting, perform
read operations twice on the same address in the flash memory, and perform polling until the same data is read.
When the security program setting is being made, bit 6 is reversed each time a read is performed.
If the security program is enabled, the flash memory is read protected in parallel PROM mode, and the flash
