(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, SCI-A, SCI-B, SCI-C, eCAN-A, and I2C-A ports.
  • The hardware multiplier is exercised.
  • Watchdog is reset.
  • ADC is performing continuous conversion.
  • 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 F2805x devices that do not have CLA, subtract the IDD current number for CLA (see Table 7-1) from the IDD (VREG disabled)/IDDIO (VREG enabled) current numbers listed in Section 7.5.1 for operational mode.
Note:

The peripheral-I/O multiplexing implemented in the device prevents simultaneous use of all available peripherals 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 the clocks to all the peripherals are turned on at the same time, the current drawn by the device will be more than the numbers specified in the current consumption tables.
