(1) IDDIO current is dependent on the electrical loading on the I/O pins.
(2) IDDA18 includes current into VDD1A18 and VDD2A18 pins. In order to realize the IDDA18 currents shown for IDLE, STANDBY, and HALT,
clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
(3) IDDA33 includes current into VDDA2 and VDDAIO pins.
(4) The TYP numbers are applicable over room temperature and nominal voltage.
NOTE
The peripheral - I/O multiplexing implemented in the 280x devices prevents all available
peripherals from being used at the same time. This is because more than one peripheral
function may share an I/O pin. It is, however, possible to turn on the clocks to all the
peripherals at the same time, although such a configuration is not useful. If this is done,
the current drawn by the device will be more than the numbers specified in the current
consumption tables.
