5.10.1
If, due to timing with which a peripheral module issues interrupt requests, the module in question
is set to module standby mode before an interrupt is processed, the module will stop with the
interrupt request still pending. In this situation, interrupt processing will be repeated indefinitely
unless interrupts are prohibited.
It is therefore necessary to ensure that no interrupts are generated when a module is set to module
standby mode. The surest way to do this is to specify the module standby mode setting only when
interrupts are prohibited (interrupts prohibited using the interrupt enable register or interrupts
masked using bit CCR-1).
