Notes on CPU Rewrite Mode
The below notes applies when rewriting the flash memory in CPU
rewrite mode.
qOperation speed
During CPU rewrite mode, set the internal clock
φ to 6 MHz or less
using the XIN Divider Select Bit (bit 7 of address 001F16).
qInstructions inhibited against use
The instructions which refer to the internal data of the flash
memory cannot be used during CPU rewrite mode .
qInterrupts inhibited against use
The interrupts cannot be used during CPU rewrite mode because
they refer to the internal data of the flash memory.
qReset
Reset is always valid. When CNVSS is “H” at reset release, the
program starts from the address stored in addresses FFFA16 and
FFFB16 of the boot ROM area in order that CPU may start in boot
mode.
