This value is added to the current consumption in HALT mode or current consumption during execution when the LCD
circuit is active. Current consumption increases according to the display contents and panel load.
This value is added to the current consumption during execution in heavy load protection mode when the LCD circuit is
active. Current consumption increases according to the display contents and panel load.
This value is added to the current consumption in HALT mode or current consumption during execution when the power
voltage booster and the LCD circuit are active. Current consumption increases according to the display contents and panel load.
This value is added to the current consumption during execution in heavy load protection mode when the power voltage
booster and the LCD circuit are active. Current consumption increases according to the display contents and panel load.
This value is added to the current consumption during execution or current consumption during execution in heavy load
protection mode when the SVD circuit is active.
This value is added to the current consumption during execution when the Flash EEPROM is being erased in
self-programming mode. Note that this is not the current value when the On Board Writer is connected.
This value is added to the current consumption during execution when the Flash EEPROM is being programmed in
self-programming mode. Note that this is not the current value when the On Board Writer is connected.
