CPU Rewrite Mode
Preliminary
CPU Rewrite Mode
In CPU rewrite mode, the on-chip flash memory can be operated on (read, program, or erase) under control
of the Central Processing Unit (CPU). In CPU rewrite mode, the flash memory can be operated on by
reading or writing to the flash memory control register and flash command register. Figure BB-1, Figure BB-
2 show the flash memory control register, and flash command register respectively.
Also, in CPU rewrite mode, the CNVSS pin is used as the VPP power supply pin. Apply the power supply
voltage, VPPH, from an external source to this pin.
In CPU rewrite mode, only the user ROM area shown in Figure AA-3 can be rewritten; the boot ROM area
cannot be rewritten. Make sure the program and block commands are issued for only the user ROM area.
The control program for CPU rewrite mode can be stored in either user ROM or boot ROM area. In the CPU
rewrite mode, because the flash memory cannot be read from the CPU, the rewrite control program must
be transferred to internal RAM before it can be executed.
