Description
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:
n_{Packet Repetitions} = IPNL + 1

Description
Inter-Packet Delay Time. Defines the delay (LED OFF) between Packet
repetitions, t_IPDT, 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:
t_ISDT = [(2 X IPOFF) + 1] X t_IBT
