2) Code Word

A group of Code Bits is called a Code Word. A Code Word consists of 12 AD bits followed by one Sync Bit. The

12 AD bits are determined by the corresponding states of A0~A7, A8/D3, A9/D2, D1 and D0 pins at the time of

transmission. When the Data Type of SC5260 is used, the address bits will decrease accordingly.

For example: In the 4-Data Type where the address has eight (8) bits, the transmitting format is:

8 Address Bits 4 Data Bits Sync. Bit

SC5260 has a maximum of ten (10) Address Bits. The following diagram shows the code bits with their

corresponding pins.

The Code Bits A0~A7, A8/D3, A9/D2, D1 and D0 are determined by the states set at these pins. For example,

when the A0 (Pin No.1) is set to “1” (VCC), the Code Bit A0 is synthesized as “1” bit. In the same manner, when it

(A0 Pin) is set to “0” (VSS) or left floating, the Code Bit A0 is synthesized as a “0” or “f” bit respectively.

When SC5260 detects “1” on any of the Data Pins, it outputs a Code Word at DOUT. If the Data Pin is still in

high state (“1”) the time the Code Word transmission ends, SC5260 outputs the same Code Word. Please refer

to the diagram below:
