Restricted AREA_1 Pointer location Block Address NFC I2C Byte 0 Byte 1 Byte 2 Byte 3 3Fh 103Fh DEV_SEC_CONFIG SRAM_CONF_PROT PP_AREA_1 (LSB) PP_AREA_1 (MSB) In below example, NFC protection pointer (NFC_PP_AREA_0H) is set to 50h and PP_AREA_1 is set to 0060h, e.g. PP_AREA_1 (LSB) is 60h and PP_AREA_1 (MSB) is 00h. This example illustrates the view from NFC perspective. From I2C perspective Area 1 will be the same, however Area 0-L and Area 0-H may look different depending on I2C protection pointer. Table 70.

AFI can be configured using WRITE AFI command (see Section 8.2.3.9.1) or directly writing AFI byte to configuration memory using WRITE CONFIG command (see Section 8.2.3.2.2). Default value of AFI is 00h. From I2C perspective, this byte can be accessed with normal READ and WRITE commands as long as not locked by I2C section locks. Table 71.
