Digital temperature sensor with overtemperature alarms
7.10.1
Serial interface reset
If the SMBus master attempts to reset the SA56004X while the SA56004X is controlling
the data line and transmitting on the data line, the SA56004X must be returned to a known
state in the communication protocol. This may be accomplished in two ways:
1. When the SDATA is LOW, the SA56004X SMBus state machine resets to the SMBus
idle state if SCLK is held LOW for more than 35 ms (maximum TIMEOUT period).
According to SMBus specification 2.0 all devices are required to time-out when the
SCLK line is held LOW for 25 ms to 35 ms. Therefore, to insure a time-out of all
devices on the bus, the SCLK line must be held LOW for at least 35 ms.
2. When the SDATA is HIGH, the master initiates an SMBus START. The SA56004X will
respond properly to a SMBus START condition only during the data retrieving cycle.
After the START, the SA56004X will expect an SMBus Address byte.
