Notes to Table 4–23:

(1)

This specification is supported across all the programmable drive settings available for this I/O standard as shown

inthe I/O Structure and Features section of the Description, Architecture, and Features chapter in volume 1 of the

HardCopy Series Devices Handbook.

(2)

Drive strength varies based on pin location. Refer to the Description, Architecture, and Features chapter in the

HardCopy II Device Family Data Sheet section in volume 1 of the HardCopy Series Handbook for more information.
