P89LPC9201/9211/922A1/9241/
8-bit microcontroller with 8-bit ADC
If requests of the same priority level are pending at the start of an instruction, an internal
polling sequence determines which request is serviced. This is called the arbitration
ranking. Note that the arbitration ranking is only used to resolve pending requests of the
same priority level.
7.15.1 External interrupt inputs
The P89LPC9201/9211/922A1/9241/9251 has two external interrupt inputs as well as the
Keypad Interrupt function. The two interrupt inputs are identical to those present on the
standard 80C51 microcontrollers.
These external interrupts can be programmed to be level-triggered or edge-triggered by
setting or clearing bit IT1 or IT0 in Register TCON.
In edge-triggered mode, if successive samples of the INTn pin show a HIGH in one cycle
and a LOW in the next cycle, the interrupt request flag IEn in TCON is set, causing an
interrupt request.
If an external interrupt is enabled when the P89LPC9201/9211/922A1/9241/9251 is put
into Power-down or Idle mode, the interrupt will cause the processor to wake-up and
resume operation. Refer to Section 7.18 “Power reduction modes” for details.
