2.4.6
No power saving features are implemented in the MFR4200; the device operates only in power mode.
2.5
2.5.1
All possible MFR4200 internal interrupt sources are combined and provided to the host by means of one
available interrupt line: INT_CC#. Refer to
for more information on available interrupt sources. The type of interrupt is level sensitive.
MFR4200 has the following resets:
2.5.2
When a reset occurs, MFR4200 registers and control bits are changed to known startup states. Refer to the
respective module chapters for register reset states for information of the different kind of resets and for
register reset states.
2.5.2.1
Refer to
out of reset.
2.5.3
All interrupt sources available in the MFR4200 are controlled and indicated by the following registers:
For more information on interrupt sources, refer to

TXENn signals for the FlexRay Optical/Electrical PHY are multiplexed
with TXENn_485 signals for the RS485 interfaces. Therefore, additional
external inverters are required for these signals in the RS485 mode.
