Power Application Controller
19.2.4. Timer D
Timer D is a general purpose 16-bit timer with 2 PWM/capture and compare units. It has one pair of PWM signals going
into one dead-time controller. Timer D can be concatenated with timers A, B, and C to synchronize the PWM/capture and
compare units. It can use either ACLK or HCLK as clock input with an additional clock divider from /1 to /128.
19.2.5. Watchdog Timer
The 24-bit watchdog timer (WDT) can be used for long time period measurements or periodic wake up from sleep mode.
The watchdog timer can be used as a system watchdog, or as an interval timer, or both. The watchdog timer can use either
FRCLK or FCLK as clock input with an additional clock divider from /2 to /65536.
19.2.6. SOC Bus Watchdog Timer
The watchdog timer 2 is used to monitor internal SOC Bus communication. It will trigger device reset if there is no SOC
Bus communication to the AFE for 4s or 8s.
19.2.7. Wake-Up Timer
The wake-up timer can be used for very low power hibernate and sleep modes to wake up the micro controller periodically.
It can be configured to be 125ms, 250ms, 500ms, 1s, 2s, 4, or 8s.
19.2.8. Real-Time Clock
The 24-bit real-time clock (RTC) can be used for time measurements when an accurate clock source is used. This timer can
also be used for periodic wake up from sleep mode. The RTC uses FRCLK as clock input with an additional clock divider
from /2 to /65536.
