Example: To set the device to B standard e.g., please do the following steps.
1. Write 02h to register STANDARD, address 00h (set B standard)
2. Write 00h to register EASY_PROG, address 01h (make sure that ACTIVE = 0)
3. Write 01h to register EASY_PROG, address 01h (due to 0 to 1 transition of ACTIVE
the device is set to B standard, i.e. registers 02h to 23h are programmed
automatically according to Table 13)
4. Write 01h to register EASY_PROG, address 01h (reset ACTIVE to logic 0)
