Each status code array consists of four 32-bit words (the status word, a priority mask, a set
mask and a clear mask). The status word is similar to the error word, with each of the 32 bits
indicating a condition. The priority mask words are used to modify the behavior caused by a
change in one of the bits in the associated status words. Each bit, in any mask, operates on the
bit in the same position in the status word. For example, setting bit 3 in the priority mask
changes the priority of bit 3 in the status word.
5.2.4 Receiver Status Code
The receiver status word is included in the header of all logs. It has 32 bits that indicate certain
receiver conditions. If any of these conditions occur, a bit in the status word is set. Unlike the
error word bits, the receiver continues to operate, unless the priority mask for the bit has been
set. The priority mask bit changes the bit in the receiver status word into an error bit. Anything
that results from an error bit becoming active also occurs if a receiver status and its associated
priority mask bits are set.
5.2.5 Auxiliary Status Codes
The auxiliary status codes are only in the RXSTATUS log. The four arrays that represent the aux-
iliary 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 priority
mask 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 any
masked auxiliary bit is set. Bit 31 of the receiver status word indicates the condition of all
masked 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 for a more detailed description.
5.2.6 Set and Clear Mask for all Status Code Arrays
The other two mask words in the status code arrays operate on the associated status word in the
same way. These mask words are used to configure the bits in the status word that result in a
RXSTATUSEVENT log broadcast. The set mask is used to turn logging on temporarily while the
