REGISTER DEFINITIONS
System Status Register - SYSSR
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) and the HSSR.
VMS - Voltage Monitor Status
voltage status register (VSR) are set.
LINS - LIN Status
status register (LINSR) are set.
Analog Integrated Circuit Device Data
Freescale Semiconductor
The system status register (SYSSR) is always transferred
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 LIN
1 = LIN Status bit set
0 = None

LIN bus wake-up threshold.
This read-only bit indicates that one or more bits in the
1 = High Side Status bit set
0 = None
The MCR allows to switch between the operation modes
This write-only bit enables/disables automatic shutdown of
1 = automatic shutdown enabled
0 = automatic shutdown disabled
This write-only bit enables/disables the 30kΩ LIN pull-up
1 = LIN pull-up resistor enabled
0 = LIN pull-up resistor disabled
