REGISTER DEFINITIONS
System Status Register - SYSSR
transferred with every SPI transmission and gives a quick
system status overview. It summarizes the status of the
Voltage Monitor Status (VMS), LIN Status (LINS), High Side
Status (HSS), and the Low Side Status (LSS).
VMS - Voltage Monitor Status
VSR are set.
LINS - LIN Status
LINSR are set.
HSS - High Side Switch Status
HSSR are set.

Mode Control Register - MCR
between the operation modes and to configure the 33912.
Writing the MCR will return the VSR.
HVSE - High-voltage Shutdown Enable
the high side and the low side drivers during a high-voltage
VSOV condition.
1 = High Side Status bit set
0 = None
This read-only bit indicates that one or more bits in the
1 = Low Side Status bit set
0 = None
The Mode Control Register (MCR) allows switching
This write-only bit enables/disables automatic shutdown of
