flash_erase()

uint32_t flash_erase

(

void

)

Erase the user flash.

Erases the entire 0.5k user flash area. Must be performed only when the system clock is 18Mhz.

Returns

1 if successful, 0 if error

Definition at line 93 of file flash.c.

References iap_erase.

flash_read()

uint32_t flash_read	(	uint32_t *	src,
		uint32_t *	dest,
		uint8_t	cnt
	)

Read from the user flash.

Reads words from the 0.5k user flash area. Must be performed only when the system clock is 18Mhz.

Parameters

[in]	src	Source address The memory area to copy from. From 0x00 - 0x1FC, as long as it is word-aligned
[out]	dest	Destination address The memory area to copy to.
[in]	cnt	Number of words to read From 1 - 128 as long as (src + (cnt * 4)) < 0x200

Returns

1 if successful, 0 if error

Definition at line 79 of file flash.c.

References iap_write_read.

flash_write()

uint32_t flash_write	(	uint32_t *	dest,
		uint32_t *	src,
		uint8_t	cnt
	)

Write to the user flash.

Writes words to the 0.5k user flash area. Must be performed only when the system clock is 18Mhz.

Parameters

[in]	dest	Destination address The memory area to copy to. From 0x00 - 0x1FC, as long as it is word-aligned
[in]	src	Source address The memory area to copy from.
[in]	cnt	Number of words to write From 1-128 as long as (dest + (cnt * 4)) < 0x200

Returns

1 if successful, 0 if error
