1. No floating I/O, unless otherwise specified.
2. RTC enabled. Clock source = LSI
3. RTC enabled, LCD enabled with external V
LCD
= 3 V, static duty, division ratio = 256, all pixels active, no LCD connected.
4. RTC enabled, LCD enabled with external V
LCD
, 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.
5. LCD enabled with internal LCD booster V
LCD
= 3 V , 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD
connected.
6. Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for extenal crystal, the LSE consumption
(I
DD LSE
) must be added. Refer to Table 32.
7. RTC enabled. Clock source = LSE.
8. Wakeup time until start of interrupt vector fetch.
The first word of interrupt routine is fetched 4 CPU cycles after t
WU
.
9. ULP=0 or ULP=1 and FWU=1 in the PWR_CSR2 register.
