1. Maximum length of RESET pulse will be filtered by an internal filter on this pin.

2. Minimum length of RESET pulse, guaranteed not to be filtered by the internal filter.

3. A positive value is leakage flowing into pin with pin at VDD_HV_A/B (the GPIO supply level); a negative value is leakage

flowing out the pin with the pin at ground.

4. GPIO output transition time information can be obtained from the device IBIS model. IBIS models are recommended for

system level simulations, as discrete values for I/O transition times are not representative of the I/O pad behavior when

connected to an actual transmission line load.

5. I/O output current specifications are valid for the given reference load figure, and the constraints given in the Operating

Conditions of this document.

6. I/O timing specifications are valid for the un-terminated transmission line reference load given in the figure below. A

lumped 8pF load is assumed at the end of a 5 inch microstrip trace on standard FR4 with approximately 1.5pF/inch (25pF

total with margin).

7. To determine total switching current on any I/O supply, current values per output pin should not be incrementally summed.

I/O interfaces on the device are asynchronous to each other, so not all switching occurs at the same instant. Actual use

case must be considered.
