MC3433 3-Axis Accelerometer
Preliminary Datasheet
assume a system problem has occurred and so the I2C circuitry will be reset, the SDA pin
released and the sensor made ready for additional I2C commands.
No other changes to registers are made.
When enabled, the I2C watchdog timer does not resolve why the master did not provide
enough clocks to complete a read cycle, but it does prevent a slave from holding the bus
indefinitely.
When enabled, the timeout period is about 200mSec.
When an I2C watchdog timer event is triggered, the I2C_WDT bit in register will be set active
by the Watchdog timer hardware. External software can detect this status by noticing this bit is
active. The act of reading register 0x04 will clears the status.
