ELMOS Semiconductor AG
Two 32 bit wide decrementing timers
Timer 0 is used as a window-watchdog, so it triggers a system reset instead of an interrupt when timer value = 0
Window-watchdog timer is disabled after reset and has to be armed by software
Window-watchdog cannot be disabled or changed when armed
16 times SCI Baud rate can be configured as timer1 clk base
NOTE: watchdog will be halted during FLASH erase / program
NOTE: watchdog and timer will be halted during debug CPU halt
Window-watchdog generates an interrupt when watchdog is reset outside specified window
