CHAPTER 3 CLOCK CONTROLLER MB95630H Series 3.1 Overview Overview The New 8FX family has a built-in clock controller that optimizes its power consumption. It supports both of the external main clock and the external subclock. The clock controller enables/disables clock oscillation, enables/disables the supply of clock signals to the internal circuit, selects the clock source, and controls the internal CR oscillator and frequency divider circuits.

Page 94: Interrupts
This section describes the interrupts. ■ Overview of Interrupts The New 8FX family has 24 interrupt request inputs for respective peripheral functions, for each of which an interrupt level can be set independently to each other. When a peripheral function generates an interrupt request, the interrupt request is output to the interrupt controller.
Page 95: Interrupt Level Setting Registers (Ilr0 To Ilr5)
The interrupt level setting registers assign a pair of bits to every interrupt request. The values of interrupt level setting bits in these registers represent the priority of an interrupt request (interrupt level: 0 to 3) in interrupt processing. MN702-00009-2v0-E FUJITSU SEMICONDUCTOR LIMITED...
