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 ROM with
3 wait-states.
XCLKOUT is turned off.

current is dependent on the electrical loading on the I/O pins.

I
DDA18
includes current into V

and V
DD2A18
pins. In order to realize the I
DDA18
currents shown for IDLE, STANDBY, and HALT,
clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.

I
DDA33
includes current into V

and V

pins.

TYP numbers are applicable over room temperature and nominal voltage.
(5)
MAX numbers are at 125°C and MAX 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.
