7.4
These registers are only used in advanced modes.
7.4.1
These two registers are the same as legacy IR baud rate divisor latch in SET 1.Reg0~1. In advanced
SIR/ASK-IR mode, the user should program these registers to set baud rate. This is to prevent
backward operations from occurring.

BR_OUT - Baud Rate Clock Output
When written to 1, the programmed baud rate clock will be output to DTR pin. This bit is
only used to test baud rate divisor.
Reserved, write 0.
EN_LOUT - Enable Loopback Output
A write to 1 will enable transmitter to output data to IRTX pin when loopback operation
occurs. Internal data can be verified through an output pin by setting this bit.
