4.5 SCI Interrupt
Five different SCI interrupt flags cause an SCI interrupt whenever they are set and enabled. The interrupt
flags are in the SCI status register (SCSR), and the enable bits are in the SCI control register 2 (SCCR2).
Any of these interrupts will vector to the same interrupt service routine, located at the address specified
by the contents of memory locations $3FF6 and $3FF7.
4.6 SPI Interrupt
Two different SPI interrupt flags cause an SPI interrupt whenever they are set and enabled. The interrupt
flags are in the SPI status register (SPSR), and the enable bits are in the SPI control register (SPCR).
Either of these interrupts will vector to the same interrupt service routine, located at the address specified
by the contents of memory locations $3FF4 and $3FF5.
