TTCM bit must be kept at 0 in the CAN_MCR register (time triggered communication mode
disabled).
Workaround
None.
13.7.4
beCAN transmitted data corruption
Description
The TGT bit can be set to 1 (CAN_MTSRH and CAN_MTSRL registers sent) even if the
device is not in time triggered communication mode (TTCM set to 1). This is due to the fact
that the CAN_MDLCR register reset value is undefined, causing the TGT bit to be set to 1
whatever the value of TTCM. This leads to the corruption of last two data bytes sent.
Workaround
TGT bit in CAN_MDLCR must be initialized to 0 (CAN_MTSRH and CAN_MTSRL registers
not sent).
13.7.5
be CAN read error in slow mode
Description
The read byte may be corrupted when the CPU is in slow mode and a FIFO read operation
is performed while a message transmission is ongoing. This happens because the
transmission mailboxes and the receive FIFOs share the same address/data lines for read
and write operations.
Workaround
To prevent this problem from occurring, the CPU clock must be the master clock
(CLK_CKDIVR[2:0] = 000b) when the user application starts reading the FIFO (CPU clock
divider changed to /1). After the FIFO read operation is complete, the CPU clock divider
(slow mode) could be applied again.
