10.5.1.2 Clear Existing Packets
This is a boolean field, when set to one it deletes any existing packet rates. When set to zero existing packet
rates remain. Only one packet rate can exist per packet ID, so new packet rates will overwrite existing packet
rates for the same packet ID.
10.5.1.3 Packet Period
This indicates the period in units of the packet timer period. The packet rate can be calculated as follows.
Packet Rate = 1000000/(Packet Period x Packet Timer Period) Hz
For example if the packet timer period is set to 1000 (1 ms). Setting packet ID 20 with a packet period of 50 will
give the following.
Packet 20 Rate = 1000000/(50 x 1000)
Packet 20 Rate = 20 Hz
