Notes:
1. The interrupt vector table and interrupt routine for interrupts to be used must be allocated to an area other than the erase target area.
2. td(SR-SUS) is required until suspend is acknowledged after the FMR21 bit is set to 1.
3. When auto-erasure suspends, a flash ready status interrupt is generated.
The interrupt to enter suspend must be enabled beforehand.
