Error Word

The error field contains a 32-bit word. Each bit in the word is used to indicate an error condition. Error
conditions may result in damage to the hardware or erroneous data, so the receiver is put into an error
state. If any bit in the error word is set, the receiver sets the error strobe line, flashes the error code on
the status LED, broadcasts the RXSTATUSEVENT log on all ports (unless the user has unlogged it),
idles all channels, turns the antenna off and disables the RF hardware. To override the error state, reset
the receiver.
The receiver can be configured to generate event messages triggered by status conditions. Receiver
Error words automatically generate event messages. These event messages are output in
RXSTATUSEVENT logs (see also Section 5.5.6, Set and Clear Mask for all Status Code Arrays on page
71).
The error word is the first field after the log header in the RXSTATUS log, as shown in the example in
Figure 25.

Figure 26 shows an example of a receiver error word.
Refer to the RXSTATUS and the RXSTATUSEVENT logs in the
Manual (OM-20000129) for more detailed log descriptions. If the receiver error word indicates an error,
refer to Section 7.1, Table 10, Resolving a Receiver Error Word on Page 86.

Status Code Arrays

There are currently 4 status code arrays:
• receiver status word
• auxiliary 1 status
• auxiliary 2 status
• auxiliary 3 status
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 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.
