L99LD02
Serial peripheral interface (ST SPI standard)
64
The Global Status Byte is described here below.
The Payload (DATA Byte 0,1 & 2) is the data transferred from the slave device with every
SPI communication to the microcontroller. The Payload always follows the OpCode and the
Address bit of the actual shifted in data (In-Frame-Response).

GSBN
Global Status Bit Not
This bit is a NOR combination of the remaining bits of this register:
RSTB nor SPIE nor FE2 nor FE1 nor DE nor GW nor FS
30
RSTB
Reset Bit
The RSTB indicates a device reset. In case this bit is set, all internal Control
Registers are set to default and kept in that state until the bit is cleared.
29
SPIE
SPI Error
The SPIE is a logical OR combination of errors related to a wrong SPI
communication (SDI stuck, wrong number of clock, parity check error)
28
FE2
Functional Error 2
VS_UV_FAIL
27
FE1
Functional Error 1
OVT or BST_OUT_FAIL
