MFR4200 FlexRay Communication Controller
3.2.3.3.35
FlexRay protocol related parameter – gdDynamicSlotIdlePhase
Address 0xAA
Reset
This register defines the number of minislots used by the CC for checking the duration of the network idle
time between two consecutive frames in the dynamic segment. This includes the dynamic slot idle phase.
Writing this register is possible only during the configuration state.
The value of IDLR depends on the values of the bit duration register
Register
It can be calculated using
The value in the register must be in the range [1:15].
3.2.3.3.36
Address 0x84
Reset
This register controls the transmission of symbols in a symbol window of a communication cycle. The
register may be modified during the configuration state and during normal operation.
CHB and CHA determine whether a symbol will be transmitted on channel B or channel A, respectively.
1 – Symbol transmission enabled.
