1. No floating I/O, unless otherwise specified.
2. Guaranteed by characterization results.
3. RTC enabled. Clock source = LSI
4. RTC enabled, LCD enabled with external VLCD = 3 V, static duty, division ratio = 256, all pixels active, no LCD connected.
5. RTC enabled, LCD enabled with external VLCD, 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.

7. Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the LSE consumption
(IDD LSE) must be added. Refer to Table 33
8. RTC enabled. Clock source = LSE
9. Wakeup time until start of interrupt vector fetch.
The first word of interrupt routine is fetched 4 CPU cycles after tWU.
10. ULP=0 or ULP=1 and FWU=1 in the PWR_CSR2 register.
