FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
REGISTER DEFINITIONS
System Status Register - SYSSR
The System status register is always transferred with
every SPI transmission and gives a quick system status
overview. It summarizes the status of the Voltage Status
Register VSR, LIN Status Register LINSR, High Side Status
Register HSSR and the Low Side Status Register LSSR.
VMS - Voltage Monitor Status
This read-only bit indicates that one or more bits in the
Voltage Status Register VSR are set.
1 = Voltage Monitor bit set
0 = None
Figure 18. Voltage Monitor Status
LINS - LIN Status
This read-only bit indicates that one or more bits in the LIN
Status Register LINSR are set.
1 = LIN Status bit set
0 = None
Figure 19. LIN Status
HSS - High Side Switch Status
This read-only bit indicates that one or more bits in the
High Side Status Register HSSR are set.
1 = High Side Status bit set
0 = None
Figure 20. High Side Status
LSS - Low Side Switch Status
This read-only bit indicates that one or more bits in the Low
Side Status Register LSSR are set.
1 = Low Side Status bit set
0 = None
Figure 21. Low Side Status
Mode Control Register - MCR
Allows to switch between the operation modes and to
configure the analog die. Writing the Mode Control Register
(MCR) will return the Voltage Monitor Status Register (VMS).
HVSE - High-voltage Shutdown Enable
This write-only bit enables/disables automatic shutdown of
the High Side and the Low Side drivers during a high-voltage
VSOV condition.
1 = automatic shutdown enabled
0 = automatic shutdown disabled
MOD2, MOD1 - Mode Control Bits
These write-only bits select the operating mode and allow
to clear the watchdog in accordance with Table 11 Mode
Control Bits.
