ISO/IEC 14443 A Reader IC
11.3.1.2
Timing diagram
Figure 19
shows programming five bytes into the EEPROM.
Assuming that the MFRC530 finds and reads byte 0 before the microprocessor is able to
write byte 1 (t
prog,del
= 300 ns). This causes the MFRC530 to start the programming cycle
(t
prog
), which takes approximately 5.8 ms to complete. In the meantime, the
microprocessor stores byte 1 to byte 4 in the FIFO buffer.
If the EEPROM start byte address is 16Ch then byte 0 is stored at that address. The
MFRC530 copies the subsequent data bytes into the EEPROM input buffer. Whilst
copying byte 3, it detects that this data byte has to be programmed at the EEPROM byte
address 16Fh. As this is the end of the memory block, the MFRC530 automatically starts
a programming cycle.
Next, byte 4 is programmed at the EEPROM byte address 170h. As this is the last data
byte, the E2Ready and TxIRq flags are set indicating the end of the EEPROM
programming activity.
Although all data has been programmed into the EEPROM, the MFRC530 stays in the
WriteE2 command. Writing more data to the FIFO buffer would lead to another EEPROM
programming cycle continuing from EEPROM byte address 171h. The command is
stopped using the Idle command.
11.3.1.3
WriteE2 command error flags
Programming is restricted for EEPROM block 0 (EEPROM byte address 00h to 0Fh). If
you program these addresses, the AccessErr flag is set and a programming cycle is not
started.
Addresses above 1FFh are taken modulo 200h; see
Section 9.2 on page 12
for the
EEPROM memory organization.
