BIT1612 10-Bit Digital Video Decoder with OSD and T-CON

7.3 Slave Mode

BIT1612 提供 BiTEKbus 或 Two-Wire Serial Interface (TWSI) 兩種 Protocol 來存取 Register Sets，並由 OP4

Pin 來決定所選用的 Protocol。當 OP4 為 1，選用 BiTEKbus Protocol；當 OP4 為 0，則選用 TWSI Protocol。

7.3.1 BiTEKbus Protocol

BIT1612 可由外部 Pins (OP3 and OP2) 來決定 Slave Address，相關的 Slave Address 請參考下表。

Table 7-7 BiTEKbus Slave Address

OP3 OP2 Slave Address

0 0 Slave Address = 0x81

0 1 Slave Address = 0x83

1 0 Slave Address = 0x85

1 1 Slave Address = 0x87
