7.2.4
IRQ
This is an interrupt request flag that indicates the interrupt request status.
When an interrupt request is generated, this flag is set to “1”. When the interrupt has been accepted, the interrupt
request flag is reset to “0”.
The interrupt request flag can be read or written by the program. Therefore, when it is set to “1”, an interrupt can be
generated by the software. By writing “0” to the flag, the interrupt pending status can be canceled.
