To set this bit to “1,” w rite “0” and then “1” in succession. Make sure no interrupts or DMA transfers w ill occur
before w riting “1” after w riting “0”.
Write to this bit w hen the NMI
than the flash memory.
Enter read array mode and set this bit to “0”.
To set this bit to “1,” w rite “0” and then “1” in succession w hen the FMR01 bit = 1. Make sure no interrupts or no
DMA transfers w ill occur before w riting “1” after w riting “0”.
Write to this bit from a program in other than the flash memory.
This flag is cleared to “0” by executing the Clear Status command.
Effective w hen the FMR01 bit = 1 (CPU rew rite mode). If the FMR01 bit = 0, although the FMR03 bit can be set to “1”
by w riting “1” in a program, the flash memory is neither placed in low pow er mode nor initialized.
This status includes w riting or reading w ith the Lock Bit Program or Read Lock Bit Status command.
