Unlike the old conception in Tango where user could make a choice from a listing of "PCF7936, PCF7941" etc., the original conception confers more significant properties to the letter that follows after numbers, e.g. there is a great difference between PCF7941A and PCF7941X.

both these types is XMA availability. TMCF is the same for both types. PCF7952X Y

AUTODETECT Usually in practice a chip name is unknown. Start your work with the "Autodetect" function. Making the autodetect, Tango selects a better choice for a chip. However, Tango cannot differ HITAG2 and HITAG2+ and makes choice "HITAG2". In this case it may be necessary to change the choice manually.

ASSISTANT Assistant prevents incorrect choices of a chip type. In case of attempt to read/write a transponder of another type has been detected, the warning dialog will appear. It is possible to disable the Assistant. Assistant bases its choice on the chip IDE mark (see Figure 4). This fact means that the assistant warning is not an absolut truth and may produce false alarms.

Each HITAG chip contains an unique Device Identifier (IDE ) so called a Serial Number. Bit 7 ot 4 of the IDE serve the function of a chip type identification. Example. IDE is 2A 48 E2 16, the IDE mark is "1". 5 PCF7943* 6 PCF7941
HITAG family has reserved certain numbers for chips, see Figure 4. 7 PCF7952 8 PCF7961 9 PCF7945/53 B PCF7937

TMCF Transponder and Memory Configuration is a set of bits, located in page 3, the leftmost byte. Access to a transponder is controlled by the TMCF. Various types of transponders have different set of bits in the TMCF.

BSEL We should pay particular attention to the bit BSEL working with HITAG2+ and HITAG2+EE. The BSEL bit is the 3rd bit of the TMCF. It serves for remapping pages 4 - 7 of a transponder. At the same time the 3rd bit TMCF of HITAG2 is the ENC bit. The ENC bit controls chip access mode.
The Autodetect function is unable to distinguish HITAG2 and HITAG2+. For this reason, careful actions should be applied during the TMCF programming.
The HITAG2+EE has XMA feature and Autodetect function makes choice as "HITAG2+Ee
