P89LPC933/934/935/936
8-bit microcontroller with accelerated two-clock 80C51 core
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 P89LPC933/934/935/936 is put into
Power-down or Idle mode, the interrupt will cause the processor to wake-up and resume
operation. Refer to Section 8.15 “Power reduction modes” for details.
