Notes to Table 4–31:

(1)

For information on which I/O banks support high-speed IOEs, 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.

(2)

RD is only supported on high-speed IOEs.

(3)

The resistance tolerances for calibrated SOCT and POCT are at the time of initial calibration. If the temperature or

voltage changes over time, the tolerance may also change.

(4)

This table applies only to HC210, HC220, HC230, and HC240 devices.
