IRBeam Interrupt Enable. When asserted permits IRBeam interrupts to be
generated.
Slew Rate Control. Must be set to 1. Slew rate is used to maintain LED pulse
symmetry.
Reserved
IRBeam Symbol Quiet Zone Time. Defines the delay between symbols as a
multiple of fundamental bit-times (IBT), calculated as follows:
t_ISQZT = n_ISQZT X t_IBT
