1. Bit 7 to 4 of this page (Identifier) serve the function of a
product type (application) identifier and are set to ‘0110’
for the PCF7x41ATJ. For system compatibility reasons,
the same product type Identifier is used by PCF7x21
(KEECOR).
2. Locations marked ‘X’ are undefined and may hold any
pattern.
Consequently, the device is configured for PCF7936
(HITAG2) transponder emulation and set to INIT mode,
providing full support regarding the Monitor and Download
