Watch Counter
The Watch counter is used for wake up from sleep mode.
Interval timer: up to 64 s (Max)@ Sub Clock: 32.768 kHz
Watch dog Timer (2 channels)
A watchdog timer can generate interrupts or a reset when a
time-out value is reached.
This series consists of two different watchdogs, a "Hardware"
watchdog and a "Software" watchdog.
"Hardware" watchdog timer is clocked by the built-in low-speed
CR oscillator. Therefore, ”Hardware" watchdog is active in any
low-power consumption modes except STOP mode.
Clock Super Visor (CSV)
Clocks generated by CR oscillators are used to supervise
abnormality of the external clocks.
External Interrupt Controller Unit
Up to 16 external vectors
Include one non-maskable interrupt(NMI)
External OSC clock failure (clock stop) is detected, reset is
asserted.
External OSC frequency anomaly is detected, interrupt or
reset is asserted.
