CODE WORD

PT2260

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 PT2260 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

PT2260 has a maximum of ten (10) Address Bits. The following diagram shows the code bits with their

corresponding pins.

2 Data: A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 D1 D0 Sync Bit

4 Data: A0 A1 A2 A3 A4 A5 A6 A7 D3 D2 D1 D0 Sync Bit

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 PT2260 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, PT2260 outputs the same Code

Word. Please refer to the diagram below:
