SLOS743K – AUGUST 2011 – REVISED APRIL 2014
6.14.3.3.8 NFCID1 Number Register (0x17)
This register is used to hold the ID of the TRF7970A for use during card emulation and NFC peer-to-peer
target operations.
The procedure for writing the ID into register 0x17 is the following:
1. Write bits 5, 6, and 7 in register 0x18 to enable SDD anticollision (bit 5), and set bit 6 and 7 to select
the ID length of 4, 7, or 10 bytes.
2. Write the ID into register 0x17. This should be done using write continuous mode with 4, 7, or 10 bytes
(according to what was set in register 0x18 bits 6 and 7).
6.14.3.3.9 NFC Target Detection Level Register (0x18)
Table 6-52. NFC Target Detection Level Register (0x18)
Function: Defines level for RF wake up, enables automatic SDD and gives NFCID size. This register is supplied by Vin to ensure data
retention during complete power down.
Default: 0x00 at POR on Vin (not POR based on V DD_X ) and not reset at EN = 0
