Description
Timestamp
This function is useful to monitor if messages are
received/transmitted in appropriate order within the
expected schedule.
Message reception (concerning message received):
TCNTR value is captured to ICR1 at the SOF/EOF
timing which is determined by TCR13 set value, and
the ICR1 value is stored into this timestamp field of
the corresponding mailbox.
Message transmission (concerning message
transmitted):
Captured by TCR12 for TCNTR value when the
TXPR or TXACK bit is set. The values are stored
into this timestamp field of the corresponding
mailbox.
Message Data Fields
Used for storage for the CAN message data that is
transmitted or received. MBx[7] corresponds to the
first data byte (MSG_DATA_0) that is transmitted or
received. The bit order on the bus is from bit 15 to 0.
The initial value of this bit is undefined; it must be
initialized (by writing 0).
Local Acceptance Filter Mask for Standard ID
The STDID_LAFM filters the standard identifier of
the receive message that is stored in bits 14 to 4 of
the mailbox (MBx[0] and MBx[1]).
0: CAN base ID corresponding to the mailbox is
enabled (Care)
1: CAN base ID corresponding to the mailbox is
disabled (Don't care)
The initial values of these bits are undefined; they
must be initialized (by writing 0).
