Enables the interrupt source for
interrupt generation
rw register, value is latched after first
clock cycle after reset
Register is used as input for the HW,
the register will be cleared due to a HW
mechanism.

Description
Receiver Reset
The receive line interface except the clock and data recovery unit (DPLL)
is reset. However the contents of the control registers is not deleted.
A receiver reset should be made after switching from power down to
power up (GCR.PD = ´1´ -> ´0´).
Transmitter Reset
The transmit framer and transmit line interface excluding the system
clock generator and the pulse shaper are reset. However the contents of
the control registers is not deleted.

Description Software (SW)
SW can read and write this register
Register is read and writable by SW
Writing to the register generates a strobe
signal for the HW (1 pdi clock cycle)
Register is read and writable by SW.
