1.7.1.4 System Power Management Configuration

The Cortex-M3 processor provides various power modes. M3_CLK is gated off when in SLEEPING or SLEEPDEEP mode. SLEEPING and SLEEPDEEP signals are available at the FPGA fabric interface. Sleep mode extension handshake signals are available at the FPGA fabric interface. System power management options can be configured as shown in Figure 1-3.
