Domain Switch-Off Sequencing, Wake-Up

Sequencing, and Power Domain Switch-On

Sequencing

– Clocks

•

Integrated High-Frequency Oscillator Used

to Generate a Reference Clock (19.2, 24, 25,

and 26 MHz) for Various System and

Peripheral Clocks

•

Supports Individual Clock Enable and

Disable Control for Subsystems and

Peripherals to Facilitate Reduced Power

Consumption

•

Five ADPLLs to Generate System Clocks

(MPU Subsystem, DDR Interface, USB, and

Peripherals [MMC and SD, UART, SPI, I2C],

L3, L4, Ethernet, GFX [SGX530], and LCD

Pixel Clock)

– Power

•

Two Nonswitchable Power Domains (RTC

and Wake-Up Logic [WAKE-UP])

•

Three Switchable Power Domains (MPU

Subsystem, SGX530 [GFX], Peripherals and

Infrastructure [PER])

•

Dynamic Voltage Frequency Scaling (DVFS)

• Real-Time Clock (RTC)
