Constructor & Destructor Documentation

openmsx::AmdFlash::AmdFlash	(	const Rom &	rom,
		const std::vector< unsigned > &	sectorSizes,
		unsigned	writeProtectedFlags,
		word	ID,
		const DeviceConfig &	config,
		bool	load = true
	)

Create AmdFlash with given configuration.

Parameters

rom	The initial content for this flash
sectorSizes	A vector containing the size of each sector in the flash. This implicitly also communicates the number of sectors (a sector is a region in the flash that can be erased individually). There exist flash roms were the different sectors are not all equally large, that's why it's required to enumerate the size of each sector (instead of simply specifying the size and the number of sectors).
writeProtectedFlags	A bitmask indicating for each sector whether is write-protected or not (a 1-bit means write-wrotected).
ID	Contains manufacturer and device ID for this flash.
config	The motherboard this flash belongs to
load	Load initial content (hack for 'Matra INK')
