If the serial port interface becomes unsynchronized with

respect to the SCLK input, any attempt to clock valid

commands into the serial interface may result in unex-

pected operation. Therefor, the serial port interface

must then be re-initialized by one of the following ac-

tions:

- Drive the CS pin high, then low.

- Hardware Reset (drive RESET pin low for at

least 10 µs).

- Issue the Serial Port Initialization Sequence,

which is 3 (or more) SYNC1 command bytes

(0xFF) followed by one SYNC0 command byte

(0xFE).

If a re-synchronization is necessary, it is best to re-ini-

tialize the part either by hardware or software reset

(command 0x80), as the state of the part may be un-

known.

5.15 Register Paging

Read/write commands access one of the 32 registers

within a specified page. By default, Page = 0. To access

registers in another page, the Page Register (address

0x1F) must be written with the desired page number.
