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:
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

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).
registers in another page, the Page Register (address
0x1F) must be written with the desired page number.
Example:
Reading register 6 in page 3.
