Constructor & Destructor Documentation

AmdFlash() [1/2]

openmsx::AmdFlash::AmdFlash	(	const Rom &	rom,
		const ValidatedChip &	chip,
		std::span< const bool >	writeProtectSectors,
		const DeviceConfig &	config
	)

Create AmdFlash with given configuration.

Parameters

rom	The initial content for this flash
chip	Contains chip configuration 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).
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.)
