? 7 CXP921000A switching of piggyback mode and evaluator mode piggyback mode can be used by setting two lcc-type eprom (for upper bytes, for lower byte) and connecting to the connector of top of the chip. evaluator mode can be used by connecting in-circuit emulator cpu probe to the connector of top of the chip. piggyback mode evaluator mode p i n 1 m a r k i n g 0 1 l c c - t y p e p r o m e p r o m a d a p t o r c h i p f o r l o w e r b y t e s f o r u p p e r b y t e s c h i p c p u p r o b e 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 150k ) , and take care that v oh should not fall under 0.7v 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. k e e p p f 7 a b o v e 0 . 7 v d d d u r i n g t h i s p e r i o d . r s t p f 7 f l a s h m o d e n o r m a l o p e r a t i o n
