Trap handlers are necessary for programming/erasing flash chips and for reading
the service info from them (like IDCODE, write protect status, etc.).

There are five trap handlers now (archive Traps.zip):
 --- For JEDEC compatible flash chips ---
 fl4_dblchk.bin - for most IRD models;
 fl4_no_chk.bin - the same as above, only without checking of programming
   timeout. Useful when too many errors printed during programming, but can hang
up IRD;
 dtf2_7fe.bin - for IRDs with 32-bits databus connected to flash chips
   (Kenwood DTF-2, Pace Goldbox);
 dtf_5000.bin - for DTF's small flash (addr 50000000) which has 8 bit wide organization;
 --- For CFI compatible flash chips ---
 intel_trap.bin - tested on iNTEL 28F160 chips organized on 16-bits databus.

	Specific notes for manipulating with iNTEL chips.
1. This chips have not a command to erase entire chip, so you have to erase each
block separately. The 'Clear Chip' button in this case is used for unlock write
protected sectors.
2. Some info from datasheet:
The defAult status of all blocks upon power-up or reset is locked (states [001
]or [101]).Locked blocks are fully protected from alteration.Any Program or
Erase operations attempted on locked block will return an error on bit SR.1 of 
the status register.The status of locked block can be changed to Unlocked or 
Lock Down using the appropriate software commands.
3. The order of programming:
	- Set appropriate 'Flash start address' and 'Sector address' (Sector
address = 'Flash start address' + Sector offset in bytes (not in words)).
	- Click 'Block protect status'. If status not '0' then click 'Clear
chip' and 'Block protect status' again. If status = 0 then
	- Click 'Clear sector';
	- When enough place is cleared, point 'From address' field to proper
address, if necessary set appropriate values in 'Data length' and 'File offset'
(look at Jtag_tester_Readme(English).doc for details);
	- Click 'Write from file' and look at results ;-)
	
******** Don't forget 'Verify trap handler' after taking a trap !!!! ********

Good luck,
