ADC
I2C
All PWM pins are toggled at
100 kHz.
All I/O pins are left
unconnected.
Data is continuously
transmitted out of the SCI-A,
SCI-B, and eCAN-A ports.
The hardware multiplier is
exercised.
Code is running out of flash
with 3 wait-states.
XCLKOUT is turned off.

I
DDIO
current is dependent on the electrical loading on the I/O pins.
I
includes current into V
and V
pins. In order to realize the I
currents shown for IDLE, STANDBY, and HALT,
clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
I
includes current into V
and V
pins.
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.
