area can be used when the programming control program transferred into the RAM enters the
execution state. A stack area should be set up as required.
In the boot mode of this chip, the content in the 8-byte ID code area shown below is confirmed so
that whether or not there is a programming control program that corresponds to the chip can be
checked.
When a new programming-control program for use in boot mode is created, add the 8-byte ID
code described above to the head of the program.
Notes on Use of Boot Mode:
When the chip comes out of reset in boot mode, it measures the low period of the input at the
SCI’s RxD1 pin. The reset should end with RxD1 high. After the reset ends, it takes about 100
states for the chip to get ready to measure the low period of the RxD1 input.
Note: * The boot program area cannot be used until a transition is made to the execution state
for the programming control program transferred to the RAM. Note that the boot program
remains stored in this area after a branch is made to the programming control program.
