Section 7 Interrupt Controller
7.8.6
Interrupts of Peripheral Modules
To clear an interrupt source flag by the CPU using an interrupt function of a peripheral module,
the flag must be read from after clearing within the interrupt processing routine. This makes the
request signal synchronized with the peripheral module clock. For details, refer to section 27.6.1,
Notes on Clock Pulse Generator.
