3.4.2 TIMA0

The TIMA0 is enabled/disabled every 2s in TIMG0 interrupt, thus you can get the module-power consumption, and the work-power consumption current in RUN0 mode is about 30uA.

Table 3-6 TIMA0 Power Consumption Test Table
TIMA0 Configuration Current
Software
  • TIMA0(clock from MCLK=32MHz) period is configured as 2s
  • The test is operated in RUN0 mode
Test condition Enable TIMA0 2.239mA
Disable TIMA0 2.209mA

TIMA0 Power Consumption Test Under RUN0 Mode

Figure 3-5 TIMA0 Power Consumption Test Under RUN0 Mode

TIMA0, as well as other timer on PD1, is forced to a disable state when system goes to STOP or STANDBY mode. To restore a timer from low-power mode, a re-configuration is necessary for timer to restart counting. Use the steps below to restart a timer:

  1. Enable timer power by DL_TimerG_enablePower();
  2. Re-configure timer x: SYSCFG_DL_TIMER_x_init();
  3. Start the timer: DL_TimerG_startCounter();
