26.3.2.3.13 GTU Configuration Register 6 (GTUC6)
The communication controller accepts modifications of the register in DEFAULT_CONFIG or CONFIG
state only.
Figure 26-140 and Table 26-119 illustrate this register.

Bit Field Value Description
31-27 Reserved 0 Reads return 0. Writes have no effect.
26-16 MOD 2h-783h µT Maximum oscillator drift (in microticks). Maximum drift offset between two nodes that operate with
unsynchronized clocks over one communication cycle in µT.
15-11 Reserved 0 Reads return 0. Writes have no effect.
10-0 ASR 0-753h µT Accepted startup range (in microticks). Number of microticks constituting the expanded range of
measured deviation for startup frames during integration.
26.3.2.3.14 GTU Configuration Register 7 (GTUC7)
The communication controller accepts modifications of the register in DEFAULT_CONFIG or CONFIG
state only.
Figure 26-141 and Table 26-120 illustrate this register.

Bit Field Value Description
31-26 Reserved. 0 Reads return 0. Writes have no effect.
25-16 NSS 2h-3FFh Number of static slots. These bits configure the number of static slots in a cycle. At least two
coldstart nodes must be configured to startup a FlexRay network. The number of static slots
must be identical in all nodes of a cluster.
15-10 Reserved. 0 Reads return 0. Writes have no effect.
9-0 SSL 4h-293h Static slot length (in macroticks). These bits configure the duration of a static slot. The static slot
length must be identical in all nodes of a cluster.
