Peripheral Simulation

For NXP (founded by Philips) P89LPC924 — Power Saving Modes (Idle and Power Down)

Simulation support for this peripheral or feature is comprised of:

  • Example code which helps you get started quickly.

These simulation capabilities are described below.

Power Down Mode Example Program

The Keil Debugger fully simulates the effects of Power Down Mode. When your target program initiates Power Down Mode program execution stops until the next external interrupt is triggered or until the MCU is reset. The following example code shows how to enter Power Down Mode.

while (1)          // Repeat Forever
  PCON |= 0x02;    // Enter Power Down Mode
  count++;         // External Interrupt or Reset Wakes-up MCU
