FUNCTIONAL DEVICE OPERATIONS

LOGIC COMMANDS AND REGISTERS

REGISTER DEFINITIONS

System Status Register - SYSSR

The System Status Register (SYSSR) 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

VSR are set.

1 = Voltage Monitor bit set

0 = None

Figure 21. Voltage Monitor Status

LINS - LIN Status

This read-only bit indicates that one or more bits in the

LINSR are set.

1 = LIN Status bit set

0 = None

Figure 22. LIN Status

HSS - High Side Switch Status

This read-only bit indicates that one or more bits in the

HSSR are set.

1 = High Side Status bit set

0 = None

Figure 23. High Side Status

LSS - Low Side Switch Status

This read-only bit indicates that one or more bits in the

LSSR are set.

1 = Low Side Status bit set

0 = None

Figure 24. Low Side Status

Mode Control Register - MCR

The Mode Control Register (MCR) allows switching

between the operation modes and to configure the 33912.

Writing the MCR will return the VSR.

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

LINPE - LIN pull-up enable.

This write-only bit enables/disables the 30kΩ LIN pull-up

resistor in STOP and SLEEP Modes. This bit also controls

the LIN bus wake-up threshold.

1 = LIN pull-up resistor enabled

0 = LIN pull-up resistor disabled
