Constructor & Destructor Documentation

◆ AmdFlash() [1/2]

openmsx::AmdFlash::AmdFlash	(	const Rom &	rom,
		std::span< const SectorInfo >	sectorInfo,
		uint16_t	ID,
		Addressing	addressing,
		const DeviceConfig &	config,
		Load	load = `Load::NORMAL`
	)

Create AmdFlash with given configuration.

Parameters

rom	The initial content for this flash
sectorInfo	A span containing the size and write protected status 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).
ID	Contains manufacturer and device ID for this flash.
addressing	Specify addressing mode (11-bit or 12-bit)
config	The motherboard this flash belongs to
load	Load initial content (hack for 'Matra INK')

◆ setVppWpPinLow()

void openmsx::AmdFlash::setVppWpPinLow ( bool value )

inline

Setting the Vpp/WP# pin LOW enables a certain kind of write protection of some sectors.

Currently it is implemented that it will enable protection of the first two sectors. (As for example in Numonix/Micron M29W640FB/M29W640GB.)
