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.

The System Status Register (SYSSR) is always
This read-only bit indicates that one or more bits in the
1 = Voltage Monitor bit set
0 = None
This read-only bit indicates that one or more bits in the
1 = LIN Status bit set
0 = None
This read-only bit indicates that one or more bits in the
1 = High Side Status bit set
0 = None

Mode Control Register - MCR
between the operation modes and to configure the 33911.
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.
MOD2, MOD1 - Mode Control Bits
clearing the watchdog in accordance with
Control Bits.
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
1 = automatic shutdown enabled
0 = automatic shutdown disabled
These write-only bits select the operating mode and allow
