7. Programming Examples
A typical application with Manchester Coding and data rate RF/64 is access control with the UNIQUE Format data structure
of 64 bit as described in Figure 7-1.
Table 7-1 on page 13 describes a programming of Atmel® ATA5575M1 with UNIQUE format example data:
Digit 0, Digit 1, …, Digit 9 = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
