Notes 1. The common condition for IDD1:
- IDD includes the total current flowing into whole power pins, including the input leakage
current flowing when the level of the input pin is fixed to VDD or VSS.
- The program is running in the code flash.
2. The typical value is that when Ta=+25deg.C and VDD=5.0 V. Peripheral devices and the data
flash are stopped.
3. The maximum value is that when all peripheral devices are operating. But the A/D converter,
RTC, LCD circuit and stepper motor circuit are stopped, and the data flash and the code flash
are stated to read mode. The 16-bit wakeup timer operates with fLOCO.
