Detailed Description

General purpose timer (GPTMR) HW driver header file.

Note

These functions should only be used if the GPTMR unit was synthesized (IO_GPTMR_EN = true).

Function Documentation

neorv32_gptmr_available()

int neorv32_gptmr_available

(

void

)

Check if GPTMR unit was synthesized.

Returns

0 if GPTMR was not synthesized, 1 if GPTMR is available.

neorv32_gptmr_disable()

void neorv32_gptmr_disable

(

void

)

Disable GP timer.

neorv32_gptmr_enable()

void neorv32_gptmr_enable

(

void

)

Enable GP timer.

neorv32_gptmr_restart()

void neorv32_gptmr_restart

(

void

)

Reset GP timer's counter register.

neorv32_gptmr_setup()

void neorv32_gptmr_setup	(	uint8_t	prsc,
		uint8_t	mode,
		uint32_t	threshold
	)

Enable and configure GP timer.

Parameters

[in]	prsc	Clock prescaler select (0..7). See NEORV32_CLOCK_PRSC_enum.
[in]	mode	0=single-shot mode, 1=continuous mode
[in]	threshold	Threshold value to trigger interrupt.
