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’.
