Notes on PF7 Usage
FLASH EEPROM incorporated PF7 is also used as flash mode setting function. Note the followings:
1. "H" is output to PF7 during a reset. That is driven at comparatively high impedance (approximately 150 k
),
and take care that V
OH
should not fall under 0.7 V
DD
by the partial pressure with external circuit load
impedance.
2. When using software reset functions, PF7 may not rise enough during a reset. Switching PF7 to "H" output
prior to software reset execution or connecting pull-up resistor is recommended.
Mask ROM and piggy/evaluation chip do not have flash mode setting function. Considering that EEPROM
incorporated type is used, above countermeasure should be performed.
Keep PF7 above 0.7 V
DD
during
this period.
