1. TA = -40 to 125 °C, no floating I/O, unless otherwise specified.

2. TA > 85 °C is valid only for devices with suffix 3 temperature range.

3. Tested in production.

4. ULP=0 or ULP=1 and FWU=1 in the PWR_CSR2 register.

5. Wakeup time until start of interrupt vector fetch.

The first word of interrupt routine is fetched 4 CPU cycles after tWU.
