DTP/external interrupt and CAN wakeup function
DTP/external interrupt transfers an interrupt request generated by an external peripheral device or a data trans-
mission request to CPU, generating external interrupt request and activating expanded intelligent I/O service.
Input RX of CAN controller is used as external interrupt input.
An interrupt request input from external peripheral device to external input pins (INT7 to INT4) and RX pin, just
as interrupt request of peripheral device, generates an interrupt request. The interrupt request generates an
external interrupt and activates expanded intelligent I/O service (EI
If the expanded intelligent I/O service (EI
