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 and A8/D3 ~ A11/D0 pins at
the time of transmission. When Data Type of PT2264 is used, the address bits will decrease
accordingly.
For example: In the 4 Datas Type where the address has eight (8) bits, the transmitting format is:

PT2264 / PT2294 have a maximum of twelve (12) Address Bits, four (4) Address/Data bits. The
following diagram shows the code bits with their corresponding pins.

The Code Bits A0 ~ A7 and A8/D3 ~ A11/D0 are determined by the states of A0 ~ A7 and A8/D3 ~
A11/D0 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.
