The READY signal directly drives the green LED on the front (READY high = LED on).
Upon startup READY is inactive (LED off) until the BIOS has initialized the main peripherals,
it is set active (LED on) before booting the operating system.
Always read back the current state before programming this setup register for enabling the
watchdog!
