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 external crystal, the LSE consumption
(I
