I/O Pads and Pin Multiplexing
(1)
Pins marked (wake) can be configured to wake up the chip from hibernate or LPDS state. In the current silicon revision, any wake pin can trigger wake up from hibernate. The wake-up
monitor in the hibernate control module logically ORs these pins applying a selection mask. However, wakeup from LPDS state can be triggered only by one of the wake-up pins that can
be configured before entering LPDS. The core digital wake-up monitor uses a mux to select one of these pins to monitor.
(2)
The device supports the feeding of an external 32.768-kHz clock. This configuration frees one pin (32K_XTAL_N) to use in output-only mode with a 100K pullup.
