The following steps give an example of the power-down sequence supported by the OMAP3530/25

device.

1. Reset OMAP3530/25 device.

2. Stop all signals driven to OMAP3530/25 balls.

3. Option 1: Power down all domains simutaneously.

4. Option 2: If all domains cannot be powered down simultaneously, follow the below sequence:

Power off all complex I/O domains (vdds_mmc1, vdds_mmc1a, vdda_dac)

Power off all core domains (vdd_core, vdd_mpu_iva)

Power off all PLL domains (vdds_dpll_dll, vdds_dpll_per)

Power off all SRAM LDOs (vdds_sram)

Power off all reference domains (vdds_wkup_bg)

Power off all standard I/O domains (vdds, vdds_mem)

The OMAP3530/25 device proceeds with the power-down sequence shown in .
