MFR4200 FlexRay Communication Controller
3.2.3.3.25
FlexRay Protocol Related Parameter – pRateCorrectionOut
Address 0xDC
Reset
This register defines the maximum permitted absolute rate correction value, in microticks, to be applied
by the internal clock synchronization algorithms. This register can be written during the configuration state
only. The value of this register does not effect the external clock correction value.
3.2.3.3.26
FlexRay Protocol Related Parameter – gColdStartAttempts
Address 0xC0
Reset
The value in this register determines the maximum number of coldstart attempts that a coldstarting startup
node is allowed to make, when trying to start up the network without receiving a valid response from
another node. After this number of coldstart attempts, the CC falls back to the integration listen state and
does not perform another coldstart attempt, until the controller enters and leaves the configuration state
again. If the register is programmed with the value ‘0’, then the CC is not allowed to start communication.
Writing the coldstart maximum register is possible during the configuration state only. The value of this
register must be within the range [0:32767].
