Note:

For power consumption measurement results, please refer to the STR71x datasheet.

STOP mode

Flash in PWD mode, MVR disabled and PLL2 disabled.

1. Configure XTI to generate interrupts on P0.15.

2. Configure the EIC to acknowledge XTI interrupt.

3. Configure MVREG/FLASH to be disabled/PWD during STOP mode.

4. Set the RCLK to the CK_AF clock source.

5. Toggle the GPIO pin P0.0.

6. Stop the external oscillator using a GPIO (P0.10).

7. Enter STOP mode.

8. Enable the external oscillator.

9. Go back to step (4).

10. Clear the XTI pending bit in the XTI_ISR.

STANDBY mode

1. Set the PLL1 to 24 MHz, RCLK = PLL1 output.

2. Configure the RTC.

3. Toggle a GPIO pin.

4. Configure RTC alarm after RTC_ALARM_DELAY.

5. Enter STANDBY mode.
