Peripheral Simulation

For Atmel AT91FR4042 — Power Saving

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 Saving Dialog

The Power Saving Dialog controls the power saving mode of the ARM controller. Pressing the CPU button stops the ARM7TDMI clock and forces the processor into Idle mode. The PS_CR (Power Saving Control Register) is a write-only register. The CPU button uses this register to disable the CPU clock.

Peripheral Clock

• PC_PCSR (Peripheral Clock Status Register) displays the current status of the peripheral clock.
• US0 if set, enables the USART 0 clock.
• US1 if set, enables the USART 1 clock.
• PIO if set, enables the parallel I/O clock.
• TC0 if set, enables the Timer/Counter 0 clock.
• TC1 if set, enables the Timer/Counter 1 clock.
• TC2 if set, enables the Timer/Counter 2 clock.
