S5PC100 USER'S MANUAL (REV1.0) CLOCK CONTROLLER
CPAD means external crystal or oscillator input for system PLLs or USB OTG PHY.
PAD_27 means 27MHz crystal pad for TV-out.
VCLK_54 is generated from clock-doubler.
Audio pad means I2S and PCM codec clock.
USB_48 means 48MHz clock from USB OTG PHY.
CAM means Camera including CIS or CCD.
7.4 MEMORY CLOCK
Memory subsystem needs special clocks just for an OneNAND-controller (SCLK_ONENAND,
SCLK_ONENAND2). SCLK_ONENAND and SCLK_ONAND2 are OneNAND-operational clocks. These special
clocks are synchronous to HCLKD0 when clock source of SCLK_ONENAND and SCLK_ONENAND2 is HCLKD0.
If selected pin of MUX1nand is 0, OneNAND operates HCLKD0-synchronously. If pin is 1, OneNAND operates
HCLKD0-asynchronously.
