IPNL

Field

Bits

Description

IPNL

7:0

IRBeam Packet Looping. Sets the number of times that a Packet is repeated.

Each packet consists of repeated transmission of a Symbol. The following

equation describes the number of Packet repetitions as a function of IPNL:

nPacket Repetitions = IPNL + 1

IPOFF

Field

Bits

Description

IPOFF

7:0

Inter-Packet Delay Time. Defines the delay (LED OFF) between Packet

repetitions, tIPDT, which can range from 10μs to 255.25μs. The minimum

permitted register value is 8. The following equation describes the time delay as

a function of IPOFF and IBT:

tISDT = [(2 X IPOFF) + 1] X tIBT
