Function Documentation

static void Dataflash_SelectChipFromPage

(

const uint16_t

PageAddress

)

[inline, static]

Selects a dataflash IC from the given page number, which should range from 0 to ((DATAFLASH_PAGES * DATAFLASH_TOTALCHIPS) - 1). For boards containing only one dataflash IC, this will select DATAFLASH_CHIP1. If the given page number is outside the total number of pages contained in the boards dataflash ICs, all dataflash ICs are deselected.

Parameters:

[in]

PageAddress

Address of the page to manipulate, ranging from ((DATAFLASH_PAGES * DATAFLASH_TOTALCHIPS) - 1).

static void Dataflash_SendAddressBytes	(	uint16_t	PageAddress,
		const uint16_t	BufferByte
	)			[inline, static]

Sends a set of page and buffer address bytes to the currently selected dataflash IC, for use with dataflash commands which require a complete 24-byte address.

Parameters:

[in]	PageAddress	Page address within the selected dataflash IC
[in]	BufferByte	Address within the dataflash's buffer
