CLOCK & POWER MANAGEMENT

CLOCK & POWER MANAGEMENT
OVERVIEW
The clock & power management block consists of three parts: clock control, USB control, and power control.
The Clock control logic in S3C2410A can generate the required clock signals including FCLK for CPU, HCLK for the
AHB bus peripherals, and PCLK for the APB bus peripherals. The S3C2410A has two Phase Locked Loops (PLLs):
one for FCLK, HCLK, and PCLK, and the other dedicated for USB block (48MHz). The clock control logic can make
slow clocks without PLL and connect/disconnect the clock to each peripheral block by software, which will reduce
the power consumption.
For the power control logic, the S3C2410A has various power management schemes to keep optimal power
consumption for a given task. The power management block in the S3C2410A can activate four modes: NORMAL
mode, SLOW mode, IDLE mode, and Power_OFF mode.
NORMAL mode: the block supplies clocks to CPU as well as all peripherals in the S3C2410A. In this mode, the
power consumption will be maximized when all peripherals are turned on. It allows the user to control the operation of
peripherals by software. For example, if a timer is not needed, the user can disconnect the clock to the timer to
reduce power consumption.
SLOW mode: Non-PLL mode. Unlike the Normal mode, the Slow mode uses an external clock (XTIpll or EXTCLK)
directly as FCLK in the S3C2410A without PLL. In this mode, the power consumption depends on the frequency of
the external clock only. The power consumption due to PLL is excluded.
IDLE mode: the block disconnects clocks (FCLK) only to the CPU core while it supplies clocks to all other
peripherals. The IDLE mode results in reduced power consumption due to CPU core. Any interrupt request to CPU
can be woken up from the Idle mode.
Power_OFF mode: the block disconnects the internal power. So, there occurs no power consumption due to CPU
and the internal logic except the wake-up logic in this mode. Activating the Power_OFF mode requires two
independent power sources. One of the two power sources supplies the power for the wake-up logic. The other one
supplies other internal logics including CPU, and should be controlled for power on/off. In the Power_OFF mode, the
second power supply source for the CPU and internal logics will be turned off. The wakeup from Power_OFF mode
can be issued by the EINT[15:0] or by RTC alarm interrupt.
