11.3.2.1 ReadE2 command error flags
11.4.1.1 Register assignment
11.3.2 ReadE2 command 03h
11.4.1 LoadConfig command 07h
11.4 Diverse commands
Table 137. ReadE2 command 03h
The ReadE2 command interprets the first two bytes stored in the FIFO buffer as the
EEPROM starting byte address. The next byte specifies the number of data bytes
returned.
When all three argument bytes are available in the FIFO buffer, the specified number of
data bytes is copied from the EEPROM into the FIFO buffer, starting from the given
EEPROM starting byte address.
The ReadE2 command can only be triggered by the microprocessor and it automatically
stops when all data has been copied.
Reading is restricted to EEPROM blocks 8h to 1Fh (key memory area). Reading from
these addresses sets the flag AccessErr = logic 1.
Addresses above 1FFh are taken as modulo 200h; see
EEPROM memory organization.
Table 138. LoadConfig command 07h
The LoadConfig command interprets the first two bytes found in the FIFO buffer as the
EEPROM starting byte address. When the two argument bytes are available in the FIFO
buffer, 32 bytes from the EEPROM are copied into the Control and other relevant
registers, starting at the EEPROM starting byte address. The LoadConfig command can
only be started by the microprocessor and it automatically stops when all relevant
registers have been copied.
The 32 bytes of EEPROM content are written to the MFRC500 registers 10h to register
2Fh; see
Remark: The procedure for the register assignment is the same as it is for the StartUp
initialization (see
address for the startup initialization is fixed to 10h (block 1, byte 0). However, it can be
chosen with the LoadConfig command.
