Implemented new template. Added part number CY7C68320C-56PVXC to

 

 

 

 

the Ordering Information. Corrected part numbers on figure 5 and 6. Moved

 

 

 

 

figure titles to the top of each figure per new template requirements. Made

 

 

 

 

grammatical corrections. Changed the Fused Memory Data section. Added

 

 

 

 

new figure: 56-pin SSOP (CY7C68320C/CY7C68321C).

 

 

 

 

Changed figure 10 to reflect actual Flow for Operational Mode. Changes

 

 

 

 

made between “VBUS_ATA_ENABLE PIN HIGH?” and “Board Manufac-

 

 

 

 

turing Test Mode”. Formatted “0=”, “1=” lines in Configuration Data Organi-

 

 

 

 

zation to always show up in the same order. Re-worded 3rd bullet point in

 

 

 

 

the Operation Selection Flow section.

 

 

 

 

GPIO2_nHS function removed and corrected the sense of ATA_EN to allow

 

 

 

 

drive on ‘0’ and Hi-Z on ‘1’.
