All PWM pins are toggled at 40 kHz.
All I/O pins are left unconnected.

current is dependent on the electrical loading on the I/O pins.
(3) In order to realize the I
DDA
currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by
writing to the PCLKCR0 register.
(4) The TYP numbers are applicable over room temperature and nominal voltage.
(5) The following is done in a loop:
• Data is continuously transmitted out of SPI-A and SCI-A ports.
• The hardware multiplier is exercised.
• Watchdog is reset.
• ADC is performing continuous conversion.
• COMP1/2 are continuously switching voltages.
• GPIO17 is toggled.
(6) If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the on-chip crystal oscillator.
