Figure 44: Status Code Arrays
9.3.4 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.
9.3.5 Auxiliary Status Codes
The auxiliary status codes are only in the
RXSTATUS
log. The four arrays that represent the auxiliary status
codes indicate the receiver state for information purposes only. The events represented 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 auxiliary 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
corresponds to the auxiliary 2 status word and bit 29 to the auxiliary 3 status word.

log in the
OEM7 Commands and Logs Reference Manual

description.
9.3.6 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 bit changes from the 0 to 1 state. The
clear mask is used to turn logging on temporarily while the bit changes from a 1 to a 0 state. Note the error
word does not have any associated mask words. Any bit set in the error word results in a
RXSTATUSEVENT
log broadcast (unless unlogged).
