MFR4200 FlexRay Communication Controller

Address 0x4

DIAGSTOP — Diagnosis Stop State Bit
When this bit is set by the host, the CC immediately enters the Diagnosis Stop state. Any ongoing
transmission or reception is aborted, and synchronization with the FlexRay communication bus is lost.
When this bit is cleared by the host, the controller enters the configuration state.
1 – The CC is in the Diagnosis Stop state.
0 – The CC is not in the Diagnosis Stop state.
SCM0, SCM1 — Serial Communication Mode Bits 0 and 1
These bits define the type of bus driver connected to the controller. It can be written during the
configuration state only.

Configuration Registers
Module Configuration Register 0 (MCR0)
Setting the CONFIG bit and writing to other bits in this register can be done
in separate instructions only. Trying to set CONFIG and change other bits at
the same time will change CONFIG only — the other bits will not be
changed. Clearing CONFIG and writing to other bits in the MCR0 can be
done simultaneously in one instruction.
