Data Sheet
20
Zarlink Semiconductor Inc.
If a slave receiver does not acknowledge after any byte, then the master generates a Stop condition and aborts the
transfer.
If a master receiver does not acknowledge after any byte, then the slave transmitter must release the SDA line to let
the master generate the Stop condition.
2.5.5 Data
After the first byte containing the address, all bytes that follow are data bytes. Each byte must be followed by an
acknowledge bit. Data is transferred MSB first.
2.5.6 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 I
2
C interface serves the function of configuring the MVTX2604 at boot time. The master is the MVTX2604 and
the slave is the EEPROM memory.
2.6 Synchronous Serial Interface
The synchronous serial interface serves the function of configuring the MVTX2604, not at boot time, but via a PC.
The PC serves as master and the MVTX2604 serves as slave. The protocol for the synchronous serial interface is
nearly identical to the I
2
C protocol. The main difference is that there is no acknowledgment bit after each byte of
data transferred.
The unmanaged MVTX2604 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 MVTX2600AG.
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.
