Template engine registers

Register mapping in NVM

Every template has 1 to 16 configuration registers. This block of registers is stored in the Page 3 of the NVM starting at address 0300 for template 0, 0310 for template 1, 0320 for template 2, etc.

For the ease of reading, notation 03tn will often be used for the address of “register n within template t”.

Registers for the NFC/RFID HF templates

This paragraph covers only SpringCore devices featuring a NFC/RFID HF interface.

The NFC/RFID HF templates are numbered 1 to 4.

Template 1 stores its configuration in non-volatile memory over addresses 0310 to 031F, template 2 over addresses 0320 to 032F, template 3 over addresses 0330 to 033F and template 4 over addresses 0340 to 034F.

Registers for the Bluetooth template

This paragraph covers only SpringCore devices featuring a BLE interface.

There is a single Bluetooth template, numbered 0.

Its configuration in non-volatile memory over addresses 0300 to 030F.

Registers for the RFID UHF template

This paragraph covers only SpringCore devices featuring a RFID UHF interface.

There is a single RFID UHF template, numbered 7.

Its configuration in non-volatile memory over addresses 0370 to 037F.

List of registers in every template

Address Nickname Title Description
03t0 LKL Technology Selector Tells the Template engine which technology or technologies it shall look for and which transaction it shall runs other the found card/tag/peer
03t1 TOF Output Format Controls how the data is understood (text or binary namely) and formatted (decimal, hexadecimal, as is…) before being sent to the host
03t2 PFX Output Prefix Defines a template-specific prefix to be sent before the data (this allows to discriminate if many templates may get the same data from different technologies)
03t3 LOC Location This register is used in some Templates to define an offset or a few advanced transaction parameters (AID, File ID, …)
03t4 OPT Options Misc. option register
03t5 AUT Authentication This register is used in some Templates to define an authentication key and/or secure communication parameters
