MFR4200 FlexRay Communication Controller
3.2.3.4.2
FlexRay protocol related parameter – vCycle
Address 0x0A
Reset
This register provides the current cycle counter value (bits CCCV[4:0]). The register is cleared by a hard
reset or when leaving the configuration state. If the maximum value is reached, the counter wraps around
to zero and continues counting.
The current cycle counter value is measured in communication cycles.
3.2.3.4.3
FlexRay protocol related parameter – vMacrotick
Address 0x08
Reset
This register indicates the current cycle time in macroticks (bits CMCV[13:0]. The register is cleared by a
hard reset or when leaving the configuration state. The CC increments the register during the cycle, and
clears it at the start of a new cycle.
