3.9.14 Error Handling
The following table shows the SCU errors and the way they should be handled
Table SCU (Sensor Control Unit)-723 Errors and their Handling
Resource Cause
SPI SPI transfer timeout (650240 SCU
clock cycles elapsed when reading
out data from the FIFO)
I2C A Master On Hold error was returned
from the I2C functional block
Sequencer Withdrawal of the suspend interrupt
request was not in time by the next
execution of the MATH_PROC
ADCIF The FIFO for the LPADC ch.n within
the ADCIF has overflowed
ADCIF The FIFO for the HPADC ch.n within
the ADCIF has overflowed
ADCIF An abnormal readout from the FIFO
within the ADCIF has occurred
ADCIF The FIFO partition D0_Rn has
overflowed
ADCIF The FIFO partition D1_Rn has
overflowed
ADCIF The FIFO partition Nn_R1 has
overflowed
ADCIF The FIFO partition Dn_R3 has
overflowed
ADCIF The FIFO for the LPADC ch.n within
the ADCIF was empty but read out
ADCIF The FIFO for the HPADC ch.n within
the ADCIF was empty but read out
ADCIF The FIFO partition D0_Rn was
empty but read out
ADCIF The FIFO partition D1_Rn was
empty but read out

How to handle on CPU
Check the SPI setting and choose a setting that
does not cause timeout.
Check the slave address of the target and
perform the transfer again. The I2C functional
block is disabled by the firmware of the SCU
internal sequencer
None. When sample data loss occurs, this can
be known by the time stamp shift.
