1. Limits are guaranteed by design and not production tested.

2. The RESET short−circuit current is the maximum pull−up current when reset is driven low by a bidirectional output.

3. WDI is internally serviced within the watchdog period if WDI is left open.

4. RESET for CAT705 & CAT706 & RESET for CAT813.

5. Not 100% tested but guaranteed by design.
