The clock & power management block consists of three parts: clock control, USB clk control, and power control.
Clock control logic
The Clock control logic in S3C2410X can generate the required clock signals including FCLK for CPU, HCLK for
the AHB bus peripherals, and PCLK for the APB bus peripherals.
The S3C2410X has two Phase Locked Loops
(PLLs): on
can make slow clocks without PLL and connect/disconnect the clock to each peripheral block by software, which
will reduce the power consumption.
The main clock source comes from an external
crystal (XTIpll) or an external clock (EXTCLK). The clock generator includes an oscillator (Oscillation Amplifier),
which is connected to an external crystal, and also has two PLLs (Phase-Locked-Loop), which generate the high
frequency clock required in the S3C2410X.
