• Manufacturer Part Number: mfr4200
• Description: Flexray Communication Controllers
• Manufacturer: Freescale Semiconductor, Inc

C.6
The implementation is compliant with PS V1.1, with the following exceptions.
C.7
C.7.1
The implementation is compliant with PS V1.1.
C.7.2
The functionality of the wakeup is implemented in part only. The controller can generate wakeup symbols
on configurable channels and repeat them for a configurable number of times in accordance with
WAKEUP SEND.
WAKEUP LISTEN is not implemented. After completing WAKEUP SEND, the controller returns to the
CONFIG state.
C.7.3
Clearing the coldstart inhibit bit after leaving 'PC_RESET' is not supported in MFR4200. This applies for
the following subsections.
C.7.3.1
The implementation is compliant with PS V1.1.
C.7.3.2
The implementation is compliant with PS V1.1.
C.7.3.3
The implementation is compliant with PS V1.1.
C.7.3.4
The implementation is compliant with PS V1.1. However, the protocol state indicated in the host interface
is incorrect for a short time, in the following case:
When the node has unsuccessfully performed a coldstart, and the number of remaining coldstart attempts
is 0, the host interface indicates that the controller has entered the coldstart listen state, and will change to
the integration listen state only after approximately one macrotick.
