5 23 CURRENT LINK ERROR COUNT REGISTER (CLECR)
The Current Link Error Count Register takes a snap-shot of the Link Error Monitor Counter during every Control Bus Interface
read cycle of this register
During a Control Bus Interface write cycle the Control Bus Write Command Reject bit (CCR) of the Interrupt Condition Register
(ICR) will be set to 1 and will ignore a write cycle
