NOTE: CHI command RESET_STATUS_INDICATORS (SUCC1.CMD = Ah) resets flags FSI, HRQ,
CSNI, CSAI, the slot mode SLM, and the wakeup status WSV.
26.3.2.4.2 Communication Controller Error Vector (CCEV)
Reset by CHI command RESET_STATUS_INDICATORS or by transition from HALT to
DEFAULT_CONFIG state or when entering READY state.
Figure 26-147 and Table 26-126 illustrate this register.

Table 26-126. Communication Controller Error Vector Register (CCEV) Field Descriptions
Bit Field Value Description
31-13 Reserved 0 Reads return 0. Writes have no effect.
12-8 PTAC 0-1Fh Passive to active count. Indicates the number of consecutive even / odd cycle pairs that have
passed with valid rate and offset correction terms, while the node is waiting to transit from
NORMAL_PASSIVE state to NORMAL_ACTIVE state. The transition takes place when PTAC
equals PTA - 1 as defined in the SUC configuration register 1.
7-6 ERRM Error mode. Indicates the actual error mode of the POC.
0 ACTIVE
1h PASSIVE
2h COMM_HALT
3h Reserved
5-4 Reserved 0 Reads return 0. Writes have no effect.
3-0 CCFC 0-Fh Clock correction failed counter. The clock correction failed counter is incremented by 1 at the end
of any odd communication cycle where either the missing offset correction error or missing rate
correction error are active. The clock correction failed counter is reset to 0 at the end of an odd
communication cycle if neither the offset correction failed nor the rate correction failed errors are
active. The clock correction failed counter stops at 15.
