Public Attributes
Indicators the chip sets for itself
bool	tamper_alarm {}
	The tamper loop has been broken.
bool	external_supply {}
	A supply is present on the chip's input.
Cleared when the tag loses power
bool	invert_output {}
bool	transparent_mode {}
bool	raw_data_mode {}
Kept until something changes them
bool	conditional_range {}
	Reduce the range when the condition holds.
bool	conditional_short {}
	Which state of the condition is the one that reduces it.
bool	max_backscatter {}
	Answer as loudly as the chip can. Set from the factory.
bool	digital_output {}
	Reduce the range when the condition holds.
bool	range_reduction {}
	G2iM+ only.
bool	protect_user {}
	User memory reads back as zeroes.
bool	protect_epc {}
	EPC reads back as zeroes.
bool	protect_tid {}
	TID reads back as zeroes.
bool	psf_alarm {}

Detailed Description

Config-Word of an NXP UCODE G2iM or G2iM+, spelled out.

Three kinds of bit live in this word. Two are indicators the chip sets for itself and no command can change. Three are temporary and go back to zero when the tag loses power. The rest are permanent and are what a toggle is usually aimed at

Warning

This is the layout of the UCODE G2iM and G2iM+ alone (SL3S1003_1013 Rev3.7 Table 13 and Table 14). Other NXP chips keep a Config-Word too and lay it out differently
