• Description: Flexray Communication Controllers
• Manufacturer: Freescale Semiconductor, Inc

0 – Symbol transmission disabled.
3.2.3.3.37
Address 0x8A
Reset
This register controls the transmission of wakeup symbols. The register may be modified in the
configuration state only.
CHB and CHA determine whether a wakeup symbol will be transmitted on channel B or channel A,
respectively.
1 – Wakeup symbol transmission enabled.
0 – Wakeup symbol transmission disabled.
CNT[4:0] determine the number of wakeup symbols to be transmitted. The controller will transmit at least
two wakeup symbols if wakeup symbol transmission is enabled.
3.2.3.3.38
FlexRay protocol related parameter – gdWakeupSymbolTxIdle
Address 0xEA
Reset
This register controls the duration of the idle period of wakeup symbols. Bits CNT[7:0] determine the
duration of the idle period in bit durations on the network. The register may be modified in the
configuration state only.
