7.5.7 MFRC52X control commands
RC_ReadRegister
Read the content of one or more register(s) of the connected reader chip.
The command allows the reading of 255 registers with one command. If a register
address is listed more than once in the data field, the content of this register will be
re-read every time.
The SAM does not check if the address of the MFRC52X is a valid register address.
RC_WriteRegister
Write the content of one or more register(s) of the connected reader chip.
The command allows the writing to 127 registers with one command. If a register address
with its related content is listed more than once in the data field, the content of this register
will be re-written every time.
The SAM will not check if the address of the MFRC52X is a valid register address.
RC_RFControl
This command allows the radio frequency field to be turned off and on. The basic behavior
is the reset functionality where the controller turns off the field for the time given in the
data field. If a zero value is passed, the field is totally turned off. After turning off the field,
to turn it on again, the command can be issued with any value other than zero. Take into
account that the passed time value also in this case will force the SAM to wait this
additional time until turning on the field again.
The unit for the time value is milliseconds.
RC_Init
Establishes the serial connection between SAM and MFRC52X and initializes the reader
chip with the register values stored in the selected register value set.
RC_LoadRegisterValueSet
Stores a customer defined register value set for the MFRC52X in the non-volatile memory
of the SAM. This set can then be used for initializing the reader chip with the RC_Init
command. The address and the related value for the register have to be placed
consecutively in the command data field of the APDU.
A register value set can store a maximum of 31 initialization values.
