TMPM361F10FG 1 Serial bus interface There are restrictions on the use of I2C bus mode when the multi-master function is used.
1.
1 Description When the multi-master function is used in I2C bus mode, if these masters start the communications simultaneously, the following phenomena may occur: 1.
Communications may be locked up.
2.
SCL pulse widths shorten; therefore these pulses may not satisfy I2C Specifications.
1.
2 Condition These phenomena occur only when the multi-master function is used in I2C bus mode.
If a single master is used, these phenomena do not occur.
1.
3 Workaround There is no workaround for these phenomena.
Perform recovery process by software.
1.
4 How to Recover from These Phenomena Perform recovery process by software.
By using a timer, add timeout process to check whether communication is in a lock-up state.
An example of recovery process: 1.
Start a timer count synchronously with start of the transmission.
2.
If a serial interface interrupt (INTSBIx) does not occur in a certain period, the MCU determines the timeout.
3.
If the MCU determines the timeout, communications may be locked up.
Perform software reset on the serial bus interface circuit.
This circuit is initialized to release communication from the lock up state.
4.
Resend transmission data.
