No floating I/O, unless otherwise specified.

RTC enabled. Clock source = LSI

RTC enabled, LCD enabled with external VLCD = 3 V, static duty, division ratio = 256, all pixels active, no LCD connected.

RTC enabled, LCD enabled with external VLCD, 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD connected.

LCD enabled with internal LCD booster VLCD = 3 V, 1/4 duty, 1/3 bias, division ratio = 64, all pixels active, no LCD

connected.

Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the LSE consumption



(IDD LSE) must be added. Refer to Table 29.
