(4) Serial I/O interrupt
This is an interrupt request from the clock synchronous serial I/O
function.
(5) f(XIN)/4096 interrupt
The f (XIN)/4096 interrupt occurs regularly with a f(XIN)/4096 pe-
riod. Set bit 0 of the PWM mode register 1 to “0.”
(6) Data slicer interrupt
An interrupt occurs when slicing data is completed.
(7) Multi-master I2C-BUS interface interrupt
This is an interrupt request related to the multi-master I2C-BUS
interface.
(8) Timer 5 6 interrupt
An interrupt is generated by an overflow of timer 5 or 6. Their
priorities are same, and can be switched by software.
(9) BRK instruction interrupt
This software interrupt has the least significant priority. It does
not have a corresponding interrupt enable bit, and it is not af-
fected by the interrupt disable flag I (non-maskable).
