Peripheral Simulation

For Freescale Semiconductor MC9328MX21 — 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

Power Control

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

  • 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.
