Chapter 4 Built-In Status TestsOEM7 Installation and Operation User Manual v1 744.4.3 Status Code ArraysThere are currently 4 status code arrays:l receiver status wordl auxiliary 1 statusl auxiliary 2 statusl auxiliary 3 statusEach status code array consists of four 32-bit words (the status word, a priority mask, a setmask and a clear mask). The status word is similar to the error word, with each of the 32 bitsindicating a condition. The priority mask words are used to modify the behavior caused by achange in one of the bits in the associated status words. Each bit, in any mask, operates on thebit in the same position in the status word. For example, setting bit 3 in the priority maskchanges the priority of bit 3 in the status word.Figure 30: Status Code Arrays4.4.4 Receiver Status CodeThe receiver status word is included in the header of all logs. It has 32 bits that indicate certainreceiver conditions. If any of these conditions occur, a bit in the status word is set. Unlike theerror word bits, the receiver continues to operate, unless the priority mask for the bit has beenset. The priority mask bit changes the bit in the receiver status word into an error bit. Anythingthat results from an error bit becoming active also occurs if a receiver status and its associatedpriority mask bits are set.4.4.5 Auxiliary Status CodesThe auxiliary status codes are only in the RXSTATUS log. The three arrays that represent theauxiliary status codes indicate the receiver state for information purposes only. The events rep-resented by these bits typically do not cause receiver performance degradation. The prioritymask for the auxiliary codes does not put the receiver into an error state. Setting a bit in the aux-iliary priority mask results in the corresponding bit in the receiver status code to be set if anymasked auxiliary bit is set. Bit 31 of the receiver status word indicates the condition of allmasked bits in the auxiliary 1 status word. Likewise, bit 30 of the receiver status word cor-responds to the auxiliary 2 status word and bit 29 to the auxiliary 3 status word.Refer also to the RXSTATUS log in the OEM7 Commands and Logs Reference Manual (OM-20000169) for a more detailed description.
