 ## **Description**
 
 ## **How To Use The Chip**
+This chip uses the UART port for main communication. This communication port is use to send instructions and receive the requested output. 
+The input is a 52 bit word for communication. In order to fill up the word the values are send one by one via the UART port.
+The 52 bit are divided in this well defined sections:
+- [51:48] 4 bit operation code.
+- [47:43] 5 bit primary register operation. 
+- [42:0]  43 bit auxiliary values.
+
+As commented the communication is throw the UART port, and each 4 bits are codification in hex. Because UART uses the ASCII table for the characters, the following list is the translation between the ASCII characters and the hex value interpreted by the chip:
+
+
+- 1 ➜ 1
+- 2 ➜ 2
+- 3 ➜ 3
+- 4 ➜ 4
+- 5 ➜ 5
+- 6 ➜ 6
+- 7 ➜ 7
+- 8 ➜ 8
+- 9 ➜ 9
+- : ➜ A
+- ; ➜ B
+- < ➜ C
+- = ➜ D
+- \> ➜ E  
+- ? ➜ F
+
+The sended data is stored in a shift register, so in order to confirm that the command is fully sended, the ASCII character **0D** (New line) needs to be send. If you want to clear the instruction sended you can send the ASCII character **20** (Space) in order to clear the shift registers. 
+### **Instruction Set**

+#### **IWrite instructions**
+| Type  | Description | OP Code [51:48] | Primary Register [47:43] | Auxillary [42:0] |
+|---|---|---|---|---|
+| IWrite | Write a logic 1 in the selected register <br>and is maintained Auxillary number of cycles | 0000 | register | cycles |
+| IWrite | Waits 1 Second and writes a logic 1 in <br>the selected selected register and is <br>maintained Auxillary number of cycles | 0001 | register | cycles |
+| IWrite | Waits Auxillary number of cycles and <br>writes a logic 1 in the selected selected <br>register and is maintained Auxillary number of cycles | 0010 | register | cycles |
+
+#### **IRead instructions**
+| Type  | Description | OP Code [51:48] | Primary Register [47:43] | Auxillary [42:0] |
+|---|---|---|---|---|
+| IRead | Reads the logic value in the selected register <br>and the read is delayed by Auxilar number of cycles | 1000 | register | cycles |
+| IRead | Reads delayed by 1 Second and reports the a <br>logic value in the selected selected register | 1001 | register | Not/use |
