The following peripheral
clocks are enabled:
• ePWM1/2/3/4/5/6
• eCAP1/2/3/4
• eQEP1/2
• eCAN-A
• SCI-A/B
• SPI-A
• 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.
Flash is powered down.
XCLKOUT is turned off.
The following peripheral
clocks are enabled:
• eCAN-A
• SCI-A
• SPI-A
• I2C
Flash is powered down.
Peripheral clocks are off.
Flash is powered down.
Peripheral clocks are off.
Input clock is disabled.

(1) I_DDIO current is dependent on the electrical loading on the I/O pins.
(2) I_DDA18 includes current into V_DD1A18 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.
(3) I_DDA33 includes current into V_DDA2 and V_DDAIO 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.
