protectection after execution of EINIT.
PDCON must be programmed to ’10’ (RTC = Off, Ports = On) during the
initialisation phase before the execution of EINIT instruction. The initial state after
reset is so defined that a reset does not interrupt the real time clock.

RTC = Off,
RTC = Off,
RTC is switched to synchronous mode. The input is derived from
the CPU clock.
RTC is switched to asynchronous mode. The input is derived
from the RTC_REF_CLK (oscillator clock).
Running on configured basic frequency.
Running on slow down frequency, PLL ON.
Running on slow down frequency, PLL OFF.
Reserved. Do not use this combination.
Main oscillator is unstable or PLL is unlocked.
Main oscillator is stable and PLL is locked.
Ports = On (default after reset).
Ports = Off.
