Doc ID 14395 Rev 7
As a consequence the length of the last bit is out of range and its reception on the bus is not
ensured.
Workaround
Check if a communication is ongoing before disabling the SPI interface. This can be done by
monitoring the BSY bit in the SPI_SR register.
13.7
beCAN interface
13.7.1
beCAN transmission error when sleep mode is entered during
transmission
Description
If sleep mode entry is requested while a transmission is ongoing or a transmission request
is pending, the beCAN TX pin will have a spurious behavior incompliant with the CAN
protocol.
No error frame will be sent and the device will enter sleep mode.
Workaround
Ensure that no transmission is ongoing and that no transmission request is pending before
putting the beCAN in sleep mode. This can be done by checking the beCAN control and
status registers before entering sleep mode. Refer to section 24.4.3 Sleep mode (low
power) of the RM0009 reference manual.
13.7.2
beCAN woken up from sleep mode with automatic wakeup
interrupt
Description
Waking up the beCAN from sleep mode using the automatic wakeup interrupt triggers an
interrupt on each CAN Rx falling edge until the bus is idle.
Workaround
To have a wakeup interrupt triggered only on the first falling edge of the CAN Rx pin, perform
the following actions:
1.
Disable the automatic wakeup interrupt.
2.
Clear the WKUI flag.
3.
Disable the sleep mode in the ISR.
13.7.3
beCAN time triggered communication mode not supported
Description
The time triggered communication mode described in section 24.4.4 of the STM8A
reference manual (RM0009) is not supported.
