beCAN CONTROLLER (Cont’d)
Bit 4 = TXOK0 Transmission OK for mailbox 0
- Read
This bit is set by hardware when the transmission
request on mailbox 0 has been completed suc-
cessfully. Please refer to
This bit is cleared by hardware when mailbox 0 is
requested for transmission or when the software
clears the RQCP0 bit.
Bits 3:2 = Reserved. Forced to 0 by hardware.
Bit 1 = RQCP1 Request Completed for Mailbox 1
- Read/Clear
This bit is set by hardware to signal that the last re-
quest for mailbox 1 has been completed. The re-
quest could be a transmit or an abort request.
This bit is cleared by software.
Bit 0 = RQCP0 Request Completed for Mailbox 0
- Read/Clear
This bit is set by hardware to signal that the last re-
quest for mailbox 0 has been completed. The re-
quest could be a transmit or an abort request.
This bit is cleared by software.
CAN TRANSMIT PRIORITY REGISTER (CTPR)
All bits of this register are read only.
Reset Value: 0000 1100 (0Ch)
Bit 7 = Reserved. Forced to 0 by hardware.
Bit 6 = LOW1 Lowest Priority Flag for Mailbox 1

mailbox are pending for transmission and mailbox
1 has the lowest priority.
Bit 5 = LOW0 Lowest Priority Flag for Mailbox 0
- Read
This bit is set by hardware when more than one
mailbox are pending for transmission and mailbox
0 has the lowest priority.
Note: These bits are set to zero when only one
mailbox is pending.
Bit 4 = Reserved. Forced to 0 by hardware.
Bit 3 = TME1 Transmit Mailbox 1 Empty
- Read
This bit is set by hardware when no transmit re-
quest is pending for mailbox 1.
Bit 2 = TME0 Transmit Mailbox 0 Empty
- Read
This bit is set by hardware when no transmit re-
quest is pending for mailbox 0.
Bit 1:0 = CODE Mailbox Code
- Read
In case at least one transmit mailbox is free, the
code value is equal to the number of the next
transmit mailbox free.
In case all transmit mailboxes are pending, the
code value is equal to the number of the transmit
mailbox with the lowest priority.
