7.13 I/O ports
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 P89LPC932A1 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”
The P89LPC932A1 has four I/O ports: Port 0, Port 1, Port 2, and Port 3. Ports 0, 1 and 2
are 8-bit ports, and Port 3 is a 2-bit port. The exact number of I/O pins available depends
upon the clock and reset options chosen, as shown in
any CCU interrupt
