• Manufacturer Part Number: ox16cf950
• Description: Cost Asynchronous Card
• Manufacturer: ETC-unknow

The programming data for each zone follows the
proceeding zone if it exists. For example a header value of
0xB127 indicates that all zones exist and they follow one
another, while 0XB123 indicates that only zone 2 and zone
3 exist.
7.3
This zone allows the user to provide custom tuple
information for the Card Information Structure (CIS),
overriding the default hard-coded tuple values found in the
device. Downloading into this zone programs the internal
RAM with the user’s tuple data and automatically sets the
source of the CIS to be this RAM, and not the hard coded
value.
Note: if the CIS is to be modified using the EEPROM,
tuple values presented to the host will be those

7.4
The Zone2 region of EEPROM contains the program value of the vendor-specific Local Configuration Registers using one or
more configuration WORDs. Registers are selected using a 7-bit byte-offset field. This offset value is the offset from address 8
(allowing addresses 0 to 7 to be reserved for function access).

Description
These bits should return 0xB12 to identify a valid program.
Once it reads this value from these bits it sets bit [TBD] in the
TBD register in the local register.
Reserved
1 = Zone 1 (CIS Configuration) data exists
0 = Zone 1 does not exist
1 = Zone 2 (Local Register Configuration) data exists
0 = Zone 2 does not exist
1 = Zone 3 (Function Access) data exists
0 = Zone 3 does not exist

programmed into the RAM. The user must ensure that
the RAM contains all the correct tuples for the
particular application.
Tuple data bytes are interrogated until the specified
number of type data-bytes have been collected in which
case the EEPROM moves over to the next zone if it exists,
or the EEPROM download terminates if no other zones are
present.
The zone contains two areas to download to:
The first WORD in this zone describes how many bytes of
data are present in each zone. The next words contain the
tuple data. The first set of WORDS contain the tuples for
the common memory (if present) followed by the tuple
WORDS for the attribute memory.
