(Flash)		 The following peripheral clocks are enabled:
  • ePWM1/2/3/4/5/6/7
  • eCAP1
  • eQEP1
  • eCAN
  • LIN
  • CLA
  • HRPWM
  • SCI-A
  • SPI-A/B
  • ADC
  • I2C
  • COMP1/2/3
  • CPU-TIMER0/1/2
All PWM pins are toggled at 60 kHz.
All I/O pins are left unconnected.(4)(6)
Code is running out of flash with 2 wait states.

(1) IDDIO current is dependent on the electrical loading on the I/O pins.
(2) To realize the IDDA currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
(3) The TYP numbers are applicable over room temperature and nominal voltage.
(4) The following is done in a loop:
  • Data is continuously transmitted out of SPI-A/B, SCI-A, eCAN, LIN, and I2C ports.
  • The hardware multiplier is exercised.
  • Watchdog is reset.
  • ADC is performing continuous conversion.
  • COMP1/2 are continuously switching voltages.
  • GPIO17 is toggled.
(5) If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the on-chip crystal oscillator.
(6) CLA is continuously performing polynomial calculations.
(7) For F2803x devices that do not have CLA, subtract the IDD current number for CLA (see Table 4-2) from the IDD (VREG disabled)/IDDIO (VREG enabled) current numbers shown in Table 4-1 for operational mode.

NOTE

The peripheral - I/O multiplexing implemented in the device 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.
