22.9.4.5 External CAN Time Trigger Inputs
The external CAN time trigger inputs ECTT[7:1] can be used as a transmit trigger for a
reference message. In the TC1796, these input lines are connected as shown in
Table 22-20.
22.9.4.6 DMA Request Outputs
The interrupt output lines INT_O0 to INT_O2 of the MultiCAN module can be used as a
DMA requestor and are able to trigger DMA transfers. INT_O[2:0] are connected to the
DMA controller as shown in Table 22-21.
