forms

(DS39776B), except for the anomalies described below.

1. Module: RX MAC

2. Module: Security Module

If the RX filter is configured for Promiscuous mode,

packets with a reserved packet type in the MAC

frame type field may cause the RX module to put

an incorrect packet length in the RX buffer.

Work around

When operating in Promiscuous mode, flush the

(RXFLUSH<0>) after every RX interrupt.

Date Codes that pertain to this issue:

All engineering and production devices.

When the device is performing encryption or

decryption, there is a very small chance that the

encryption or decryption result may be incorrect.

Work around

During decryption operations, repeat the decryp-

tion one or more times if a MIC error is indicated

on the first attempt.

During encryption operations, verify the encryption

by immediately decrypting the packet and check-

ing it against the original for errors. If an error is

found, repeat the encryption and verification.

3. Module: RX MAC

Under certain conditions, such as channel scan-

ning, unexpected packets may be received at

alternative channels spaced at 20 MHz intervals.

This happens when the interfering sources have

sufficient intensity and proximity to the receiver.

For example, if the device is tuned to the

2,425 MHz channel, spurious signals could be

detected

2,465 MHz.

Work around

To prevent this system degradation, do one of the

following:

• Add a “Channel ID” to the “Frame Payload” of

• Increase the distance between the nodes.

• Reduce the other nodes’ transmitted power.

This will enable the firmware to filter out

unexpected packets.
