Detailed Description

Enumeration Type Documentation

enum CLK_SRC_SEL

Defines a driver to facilitate interfacing with the auxiliary clock.

Use this driver to output a clock to a GPIO pin for external use. Two clock sources are avaliable: clk0 or clk1, as well as two base frequencies used to calulate the prescaler : 1 MHz or 24 MHz. Note that the desired GPIO pin must have already been configured to output for aclk. See the HW muxing section in the User Documentation for more information.

Function Documentation

void wiced_hal_aclk_disable

(

uint32_t

clkSrc

)

Disables the desired auxilary clock source.

Parameters

clkSrc

- Clock source to disable (aclk0 or aclk1).

Returns

none

void wiced_hal_aclk_enable	(	uint32_t	frequency,
		uint32_t	clkSrc,
		uint32_t	baseFreqSel
	)

Configures, enables, and starts the aclk to be active on a preconfigured GPIO pin.

(!) Note that the desired GPIO pin must have already been configured to output for aclk. See the HW muxing section in the User Documentation for more information.

Parameters

frequency	- Desired frequency to output; 0 is the same as disable.
clkSrc	- ACLK0 or ACLK1
baseFreqSel	- ACLK_FREQ_1_MHZ or ACLK_FREQ_24_MHZ.

Returns

none
