NOTES:
1. When the INT3 pin is used for data bus in microprocessor mode, a DMA3 interrupt request cannot be generated by an input signal to
the INT3 pin.
2. The falling edge or both edges of input signal to the INTi pin can be a DMA request source. It is not affected by the INT interrupts (bits
POL and LVS in the INTiIC register, the IFSR register) and vice versa.
3. To switch between the UARTj receive interrupt and ACK interrupt (j = 0 to 4), use the IICM bit in the UiSMR register and IICM2 bit on
the UiSMR2 register. To use the ACK interrupt, set the IICM bit to 1 (I²C mode) and the IICM2 bit to 0 (NACK/ACK interrupt).
