Fix Status

1. Faulty GPIO Interrupt

No silicon fix planned.

1. Faulty GPIO Interrupt

• PROBLEM DEFINITION

When a falling edge interrupt is enabled for a GPIO pin, reading the GPIO Port 1 coincident to a rising edge

of that GPIO signal may generate a false GPIO interrupt.

Any Port 0 or Port 1 GPIO

pin with Falling Edge GPIO

Interrupt Enabled

Port 1 Read Signal

(See Note 1)

GPIO Interrupt Signal

(See Note 2)
