Peripheral Simulation

For NXP (founded by Philips) LPC2144 — Power Control

Simulation support for this peripheral or feature is comprised of:

• Dialog boxes which display and allow you to change peripheral configuration.

These simulation capabilities are described below.

Power Control Dialog

The Power Control Dialog controls the power saving mode of the ARM controller. With this dialog, you can selectively enable or disable unused peripherals to save power.

Selected Peripheral

When checked, this box indicates that the selected peripheral is disabled. The checkbox name changes based on the peripheral selected.

Power Control Group

• PCON (Power Control Register) contains the Idle Mode bit (bit 0), and the Power Down mode bit (bit 1).
• PCONP (Power Control Peripheral Register) contains the individual power control bits for all the peripherals in the list.
• IDL (Idle Mode) if set, stops the processor clock, but leaves the other peripherals active. Any interrupt starts the processor clock again.
• PD (Power Down Mode) if set, stops the oscillator and all on-chip clocks to stop. A wakeup condition starts the oscillator and clocks again and resets this bit.
• PDBOD (Power Down Brown-Out Detect Mode) if set, forces the processor into power-down mode when a brown-out condition is detected.
• BODPDM (Brown Out Detect Power Down Mode) if set, the BOD circuitry will go into power down mode when chip power down is asserted.
• BOGD (Brown Out Global Disable) if set, fully disables the BOD circuitry at all times.
• BORD (Brown Out Reset Disable) if set, prevents the second stage of low voltage detection (2.6 V) from causing a chip reset.

Interrupt Wakeup Group

• INTWAKE (Interrupt Wakeup Register) contains following bit settings:
• RTCWAKE (Real-Time Clock Wakeup Enable) if set, wakes up the processor from power down mode.
• BODWAKE (Brown-Out Detect Wakeup Enable) if set, wakes up the processor from power down mode.
• USBWAKE (USB Wakeup Enable) if set, USB activity wakes up the processor from power down mode.
