11 / 91 page MVTX2601 Data Sheet 11 Zarlink Semiconductor Inc. 2.2.6 Stop Condition Generated by the master. The bus is considered to be free after the Stop condition is generated. The Stop condition occurs if while the SCL line is High, there is a Low-to-High transition of the SDA line. The I2C interface serves the function of configuring the MVTX2601 at boot time. The master is the MVTX2601 and the slave is the EEPROM memory. 2.3 Synchronous Serial Interface The synchronous serial interface serves the function of configuring the MVTX2601 not at boot time but via a PC. The PC serves as master and the MVTX2601 serves as slave. The protocol for the synchronous serial interface is nearly identical to the I2C protocol. The main difference is that there is no acknowledgment bit after each byte of data transferred. The unmanaged MVTX2601 uses a synchronous serial interface to program the internal registers. To reduce the number of signals required, the register address, command and data are shifted in serially through the D0 pin. STROBE- pin is used as the shift clock. AUTOFD- pin is used as data return path. Each command consists of four parts. START pulse Register Address Read or Write command Data to be written or read back Any command can be aborted in the middle by sending a ABORT pulse to the MVTX2601. A START command is detected when D0 is sampled high when STROBE- rise and D0 is sampled low when STROBE- fall. An ABORT command is detected when D0 is sampled low when STROBE- rise and D0 is sampled high when STROBE- fall. 2.3.1 Write Command STROBE- D0 START ADDRESS COMMAND DATA W A0 A1 A2 ...
