+/*************************************************************************************
+Documentation Collection by Dinesh-A - dinesh.annayya@gmail.com
+Reference: https://techdocs.altium.com/display/FPGA/NEC+Infrared+Transmission+Protocol
+
+The NEC IR transmission protocol uses pulse distance encoding of the message bits. Each pulse burst (mark – RC transmitter ON) is 
+562.5µs in length, at a carrier frequency of 38kHz (26.3µs). Logical bits are transmitted as follows:
+    Logical '0' – a 562.5µs pulse burst followed by a 562.5µs space, with a total transmit time of 1.125ms
+    Logical '1' – a 562.5µs pulse burst followed by a 1.6875ms space, with a total transmit time of 2.25ms
+
+
+When a key is pressed on the remote controller, the message transmitted consists of the following, in order:
+
+    * 9ms leading pulse burst (16 times the pulse burst length used for a logical data bit)
+    * 4.5ms space
+    * the 8-bit address for the receiving device
+    * the 8-bit logical inverse of the address
+    * the 8-bit command
+    * the 8-bit logical inverse of the command
+    * final 562.5µs pulse burst to signify the end of message transmission.
+
+Repeat Codes
+
+If the key on the remote controller is kept depressed, a repeat code will be issued, typically around 40ms after 
+the pulse burst that signified the end of the message. A repeat code will continue to be sent out at 108ms intervals, 
+until the key is finally released. The repeat code consists of the following, in order:
+
+    * 9ms leading pulse burst
+    * 2.25ms space
+    * 562.5µs pulse burst to mark the end of the space (and hence end of the transmitted repeat code).

+/************************************************
+https://techdocs.altium.com/display/FPGA/NEC+Infrared+Transmission+Protocol
+The NEC IR transmission protocol uses pulse distance encoding of the message bits. Each pulse burst (mark – RC transmitter ON) is 562.5µs in length, 
+at a carrier frequency of 38kHz (26.3µs). Logical bits are transmitted as follows:
+
+    Logical '0' – a 562.5µs pulse burst followed by a 562.5µs space, with a total transmit time of 1.125ms
+    Logical '1' – a 562.5µs pulse burst followed by a 1.6875ms space, with a total transmit time of 2.25ms
+
+When a key is pressed on the remote controller, the message transmitted consists of the following, in order:
+
+    * 9ms leading pulse burst (16 times the pulse burst length used for a logical data bit)
+    * 4.5ms space
+    * the 8-bit address for the receiving device
+    * the 8-bit logical inverse of the address
+    * the 8-bit command
+    * the 8-bit logical inverse of the command
+    * final 562.5µs pulse burst to signify the end of message transmission.
