Decrement T14 Timer Value
Setting this bit to 1 effects a decrement of the T14 timer value. The bit is
cleared by hardware after decrementation.
Increment T14 Timer Value
Setting this bit to 1 effects an increment of the T14 timer value. The bit is
cleared by hardware after incrementation.
RTC register access possible
This bit indicates that a synchronous read / write access to RTC registers
is possible. The Clock Control register RTCCLC can allways be
accessed.
ACCPOS = ‘0’: No write access is possible, only asynchronous reads.
ACCPOS = ‘1’: Read / Write access is possible
