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

3.2.3.4.4
FlexRay protocol related parameter – vOffsetCorrection
Address 0x32C
Reset
This read-only register indicates the offset correction value, in microticks, calculated by the clock
synchronization algorithm (before external offset correction and before value limitation), at the end of each
communication cycle. Data in this register is presented in 2’s complement form. The value in this register
is valid after a communication cycle start and until its NIT start. The CC modifies OCVR during the NIT.
3.2.3.4.5
FlexRay protocol related parameter – vRateCorrection
Address 0x32A
Reset
This read-only register indicates the rate correction value, in microticks, calculated by the clock
synchronization algorithm (before external rate correction and value limitation), at the end of each odd
communication cycle. Data in this register is presented in 2’s complement form.
