STATIC INLINE void Chip_CREG_EnableUSB0Phy

(

bool

Enable

)

Enables the USB0 high-speed PHY on LPC18xx/LPC43xx parts.

Parameters

Enable

: true to enable PHY, false to disable

Returns

Nothing The USB0 PLL & clock should be configured before calling this function. This function should be called before the USB0 registers are accessed.

STATIC INLINE void Chip_CREG_SetFlashAcceleration

(

uint32_t

Hz

)

Configures the onboard Flash Accelerator in flash-based LPC18xx/LPC43xx parts.

Parameters

Hz	: Current frequency in Hz of the CPU

Returns

Nothing This function should be called with the higher frequency before the clock frequency is increased and it should be called with the new lower value after the clock frequency is decreased.
