Bits [15:0] WDOG_CTRL: Write 0xDEAD to disable or 0xEABE to enable.
Event timer
The SysTick timer is an ARM® standard system timer in the NVIC. The SysTick timer can
be clocked from either the FCLK (the clock going into the CPU) or the Sleep Timer clock.
FCLK is either the SCLK or PCLK as selected by CPU_CLK_SEL (see
switching on page
Slow timers (Watchdog and Sleeptimer) control and status registers
These registers are powered from the always-on power domain.
All registers are only writable when in System mode
Watchdog general control register (WDOG_CFG)
Register bits for general top level chip functions and protection.
Watchdog bits can only be written after first writing the appropriate code to the
WDOG_CTRL register.
