CPU Rewrite Mode
Preliminary
Precautions on CPU Rewrite Mode
Described below are the precautions to be observed when rewriting the flash memory in CPU rewrite
mode.
(1) Operation speed
During erase/program mode, set BCLK to one of the following frequencies by changing the divide
ratio:
5 MHz or less when wait bit (bit 7 at address 000516) = 0 (without internal access wait state)
10 MHz or less when wait bit (bit 7 at address 000516) = 1 (with internal access wait state)
(2) Instructions inhibited against use
The instructions listed below cannot be used during CPU rewrite mode because they refer to the
internal data of the flash memory:
UND instruction, INTO instruction, JMPS instruction, JSRS instruction, and BRK instruction
(3) Interrupts inhibited against use
No interrupts can be used that look up the fixed vector table in the flash memory area. Maskable
interrupts may be used by setting the interrupt vector table in a location outside the flash memory
area.
