(Note 2)
NOTES:
1. If the INT3 pin is used as data bus in the memory expansion mode or microprocessor mode, a DMA3 interrupt
request cannot be generated by an input signal to the INT3 pin.
2. The falling edge and both edges of input signal into the INTj pin (j = 0 to 3) cause a DMA request. The INT interrupt
(the POL bit in the INTjlC register, the LVS bit, the IFSR register) is not affected and vice versa.
3. The UkSMR register and UkSMR2 register (k = 0 to 4) switch the UARTj receive to ACK or ACK to UARTk receive.
4. The same setting is used to generate an intelligent I/O interrupt 9 request and a CAN interrupt 0 request.
5. The same setting is used to generate an intelligent I/O interrupt 10 request and a CAN interrupt 1 request.
6. The same setting is used to generate an intelligent I/O interrupt 11 request and a CAN interrupt 2 request.
