CAUTION
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.

TEST CONDITIONS
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.
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.
(3) I_DDA33 includes current into V_DDA2 and V_DDAIO pins.
(4) The TYP numbers are applicable over room temperature and nominal voltage.
