26.3.2.3.3 SUC Configuration Register 3 (SUCC3)
The communication controller accepts modifications of the register in DEFAULT_CONFIG or CONFIG
state only.
Figure 26-130 and Table 26-109 illustrate this register.

Bit Field Value Description
31-8 Reserved. 0 Reads return 0. Writes have no effect.
7-4 WCF 1-Fh Maximum without clock correction fatal. These bits define the number of consecutive even/odd
cycle pairs with missing clock correction terms that will cause a transition from NORMAL_ACTIVE
or NORMAL_PASSIVE state. These must be identical in all nodes of a cluster.
Note: The transition to HALT state is prevented if SUCC1.HCSE is not set.
3-0 WCP 1-Fh Maximum without clock correction passive. These bits define the number of consecutive even/odd
cycle pairs with missing clock correction terms that will cause a transition from NORMAL_ACTIVE
to NORMAL_PASSIVE to HALT state. These must be identical in all nodes of a cluster.
26.3.2.3.4 NEM Configuration Register (NEMC)
The communication controller accepts modifications of the register in DEFAULT_CONFIG or CONFIG
state only.
Figure 26-131 and Table 26-110 illustrate this register.

6-0 NML 0-Ch bytes Network management vector length (in bytes).
These bits configure the length of the NM vector. The configured length must be identical in all
nodes of a cluster.
