P89LPC938
8-bit microcontroller with 10-bit A/D converter
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 P89LPC938 is put into Power-down or Idle
mode, the interrupt will cause the processor to wake-up and resume operation. Refer to
Section 7.15 “Power reduction modes”
for details.
