4.7 SPI Interrupt
There are two different SPI interrupt flags that 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 location $1FF4 and $1FF5.
4.8 I2C Interrupt
There is one I2C interrupt flag that causes an I2C interrupt whenever it is set and
enabled. The interrupt flag is in the I2C status register (MBSR), and the enable bits
are in the I2C control register (MBCR). This interrupt will vector to the same
interrupt service routine, located at the address specified by the contents of
memory location $1FF2 and $1FF3.
4.9 Timer 2 Interrupt
There are two different timer 2 interrupt flags that cause a timer interrupt whenever
they are set and enabled. The interrupt flags and enables are in the timer status
and control register (TCSR). Either of these interrupts will vector to the same
interrupt service routine, located at the address specified by the contents of
memory location $1FF0 and $1FF1.
