External Interrupts

PRELIMINARY V1.8

When an interrupt is generated, the interrupt request flag that generated it should be

cleared by software when the service routine is vectored. All of the interrupt request

flags can be set or cleared by software, with the same result as though it had been set or

cleared by hardware. That is, interrupt can be generated or pending interrupts can be

canceled in software. Each of these interrupt sources can be individually enabled or

disabled by setting or clearing a bit in Special Function Registers ISE0 to ISE2. And,

each of interrupt group can be enabled or disabled by setting or clearing a bit in Special

Function Register IE. The bit EA in IE contains also a global disable bit (0: disable, 1:

Enable), which disables all interrupts at once.
