Register description
The device contains a set of registers which are used to control its behavior and to retrieve
angular rate data. The registers address, made of 7 bits, is used to identify them and to write
the data through serial interface.
6.1
WHO_AM_I (0Fh)
Device identification register.
This register contains the device identifier that for LY530AL is set to D1h
6.2
CTRL_REG (20h)
TUD_SDO: When this bit is set to ‘1’ the Pull Up on SDO pin is disabled.
DIG_en: When this bit is set to ‘1’ the device is in normal mode. When DIG_en bit is ‘0’ the
device is in power down mode.
IF_SEL: Setting this bit to ‘1’ the voltage value applied to IF_DIS pin selects one of the two
digital interfaces (‘1’ for I2C only, ‘0’ for SPI only).

CTRL_REG description
TUD_SDO
Pull Up disable for SDO pin. Default value: 0
(0: Pull Up connected; 1: Pull Up disabled)
DIG_en
Power Down bit. Default value: 0
(0: Device is in power down mode; 1: Divice is in normal mode)
IF_SEL
Interface selection. Default value: 0
(0: both interfaces available; 1: IF_DIS pin value selects the interface)
BDU
Block data update. Default value: 0
(0: continuos update; 1: update inhibited)
alg
Data alignment selection bit. Default value: 0
(0: 16 bit left justified; 1: 10 bit right justified)
BOOT
Reboot of memory content. Default value: 0
(0: normal mode; 1: memory reboot)
SIM
SPI serial interface mode selection bit. Default value: 0
(0: 4-wire mode; 1:3-wire mode)
