Abstract

Error-reporting registers provide a mechanism for first error capture across one entire machine. There are error-reporting registers for each thermal conduction module (TCM), logic support station (LSS) and logic support element (LSE) in the system. The error-reporting registers (ERRs) contain the error checkers for that element and take a single-cycle picture of these checkers which is latched up in the ERRs until reset by a single command to the LSE. The ERR contents in each TCM are ORed together and sent to the LSS ERR on each board. The LSS ERR contains all the LSS error checkers and the TCM error indicator lines. The LSS ERR takes a single-cycle picture of these lines on first detected error and latches the lines up until reset by the LSE command. The ERR contents in the LSS are ORed together and sent off to the LSE.
