Notes:
1. The interrupt vector table and interrupt routine for interrupts to be used must be allocated to an area other the erase target area.
2. td(SR-SUS) is required until suspend is acknowledged after the FMR21 bit is set to 1.
The interrupt to enter suspend must be enabled beforehand.
Write the command code 20h
Write D0h to any block address
