(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) Multi-master I²C-BUS Interface Interrupt
This is an interrupt request related to the multi-master I²C-BUS
interface.
(7) A-D Conversion Interrupt
The A-D conversion interrupt occurs at the completion of A-D
conversion.
(8) 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).
