addition, make sure that V

is not released or shut off while the boot program is executing or

the flash memory is being programmed or erased.

Boot mode can be released by driving the reset pin low, waiting at least ten system clock

cycles, then releasing the application of 12 V to the MD

pins and releasing the reset.

The settings of external pins must not change during operation in boot mode.

During boot mode, if input of 12 V to the MD

pin stops but no reset input occurs at the

pin, the boot mode state is maintained within the chip and boot mode continues (but do not

stop applying 12 V to the FV

pin during boot mode

If a watchdog timer reset occurs during boot mode, this does not release the internal mode

state, but the internal boot program is restarted.

Therefore, to change from boot mode to another mode, the boot-mode state within the chip

must be released by a reset input at the

pin before the mode transition can take place.

7. If the input level of the MD

pin is changed during a reset (e.g., from 0 V to 5 V then to 12 V

while the input to the

pin is low), the resultant switch in the microcontroller’s operating

mode will affect the bus control output signals (

) and the status of ports that

can be used for address output

Threfore, either set these pins so that they do not output signals during the reset, or make sure

that their output signals do not collide with other signals outside the microcontroller.

8. When applying 12 V to the MD

pins, make sure that peak overshoot does not exceed

the rated limit of 13 V.

Also, b sure to connect a decoupling capacitor to the FV

Note: *1 For details on applying, releasing, and shutting off V

, see note (5) in section 20.7,

Flash Memory Programming and Erasing Precautions.

*2 These ports output low-level address signals if the mode pins are set to mode 1 during

the reset. In all other modes, these ports are in the high-impedance state. The bus

control output signals are high if the mode pins are set for mode 1 or 2 during the reset.

In mode 3, they are at high impedance.

*3 H'0000 to H'EF7F in mode 2 and H'0000 to H'F77F in mode 3.
