Procedure to Enter EW0 Mode
Jump to the rewrite control program transferred to a
space other than the flash memory. (In the following
steps, use the rewrite control program in a space
other than the flash memory)
NOTES :
Transfer the rewrite control program in CPU
rewrite mode to a space other than the flash
memory
Jan 10, 2006
1. In CPU rewrite mode, set the CM06 bit in the CM0 register and CM17 to 6 bits in the CM1 register to CPU
2. Set the FMR01 bit to “1” immmediately after setting it to “0” Do not generate an interrupt or a DMA transfer
3. Exit CPU rewrite mode after executing the read array command.
4. When CPU rewrite mode is exited while FMR05 bit is set to “1”, the user ROM area can be accessed.
5.When in CPU rewrite mode, the PM10 and PM13 bits in the PM1 register are set to “1”. The rewrite control
clock frequency of 10.0 MHz or less. Set the PM17 bit in the PM1 register to “1” (with wait state).
between setting the bit to “0” and setting it to “1”. Set the bit to “0”. Set this in a space other than flash
memory while the NMI pin is held “H”.
program can only be executed in the internal RAM or in an external area that is enabled for use when the
PM13 bit = 1. When the PM13 bit = 0 and the flash memory is used in 4M-byte mode, the extended
accessible area (40000h to BFFFFh) cannot be used.
Single-chip mode, memory expansion
Set CM0, CM1 and PM1 registers
