Functional Description
Functional Device Operation
Sleep Mode Sequence
The Sleep command, as shown in
Table 11
, has to be sent
twice.
Stop Mode Sequence
The Stop command, as shown in
Table 12
, has to be sent
twice.
SPI Status Register (Read)
Table 13
shows the SPI Status register bits by name.
INTSCR—Register Content Flags or Interrupt Source
This bit indicates if the register contents reflect the flags or
an interrupt/wake-up interrupt source.
1 = D6:D0 reflects the interrupt or wake-up source.
0 = No interrupt occurred. Other SPI bits report real time
status.
LINWU/LINFAIL—LIN Status Flag Bit
This bit indicates a LIN wake-up condition.
1 = LIN bus wake-up occurred or LIN overcurrent/
overtemperature occurred.
0 = No LIN bus wake-up occurred.
HVF —High-Voltage Flag Bit
This flag is set on an overvoltage (VSUP1) condition.
1 = High-voltage condition has occurred.
0 = no High-voltage condition.
LVF/BATFAIL—Low-Voltage Flag Bit
This flag is set on an undervoltage (VSUP1) condition.
1 = Low-voltage condition has occurred.
0 = No low-voltage condition.
VDDT—Voltage Regulator Status Flag Bit
This flag is set as pre-warning in case of an over-
temperature condition on the voltage regulator.
1 = Voltage regulator overtemperature condition, pre-
warning.
0 = No overtemperature detected.
HSST—High-Side Status Flag Bit
This flag is set on overtemperature conditions on one of
the high-side outputs.
1 = HSx off due to overtemperature.
0 = No overtemperature.
L2:L1—Wake-Up Inputs L1, L2 Status Flag Bit
These flags reflect the status of the L2 and L1 input
terminals and indicate the wake-up source.
1 = L2:L1 input high or wake-up by L2:L1 (first register
read after wake-up indicated with INTSRC = 1).
0 = L2:L1 input low.
