cmos::DECLARE_EXCEPTION

(

CmosException

)

Abstract base class for the cmos read write operations.

cmos::DECLARE_EXCEPTION_EX	(	InvalidCmosRWMode	,
		cmos	,
		CmosException
	)

void cmos::readByteArray	(	const ICmosRW &	cmos,
		u32	indexPort,
		u32	dataPort,
		u32	offset,
		u8 *	target,
		u32	count
	)

Read or write an array of bytes to CMOS.

This function is set up as a non-member helper function. It successively reads/writes

Parameters

count

bytes from/to CMOS.

Note that the byte array passed as a parameter need not be zero-terminated.

Parameters

cmos	Pass in the ICmosRW object to operate on
indexPort	The IO port to write the offset to
dataPort	The IO port to read/write data after setting the index via indexPort
offset	The offset within CMOS. CMOS is typically multiple 256byte pages.
target	Byte array to store the results. Call must already have allocated.
count	The number of bytes to read/write.

void cmos::writeByteArray	(	const ICmosRW &	cmos,
		u32	indexPort,
		u32	dataPort,
		u32	offset,
		const u8 *	source,
		u32	count
	)

Parameters

count

bytes from/to CMOS.

Note that the byte array passed as a parameter need not be zero-terminated.

Parameters

cmos	Pass in the ICmosRW object to operate on
indexPort	The IO port to write the offset to
dataPort	The IO port to read/write data after setting the index via indexPort
offset	The offset within CMOS. CMOS is typically multiple 256byte pages.
source	byte array to store the CMOS contents. must be allocated by caller.
count	The number of bytes to read/write.
