Registers Data Depth
In general the whole data registers consist of a data
depth of eight bits. But sometimes it is unnecessary to
implement the full depth. In such a case the invisible
bits consider like a zero.
Used Index Commands
The table shows the valid index commands, its allowable modes, and the data depth to them.

Note: The main_ctrl_1 register is written software dependent on the offset value stored in ext_ctrl_7 and ext_ctrl_8 registers.
The main_ctrl_1 register can be set to the following values, shown in the table.
Main-ctrl-0 register values
1)
APEN - Acknowledge Pulse Enable, (optional)
This bit is used to enable the acknowledge pulse. When it is set to 1 and RX OEN is 1 (receiver output enabled) the IRRX/SRDAT line will
be pulsed low for one clock cycle upon successful completion of every write command or special command with individual (non broadcast)
transceiver address. The internal signal from the receiver photo diode is disconnected when this bit is set to 1.
