Table 4. Control Bits Function (Write Operation)
Table 5. Control Bits Function (Read Operation)
HSxON—High-Side x Enable Bit
This bit enables HSx. Reset clears the HSx bit.
1 = HSx switched on (refer to Note below).
0 = HSx switched off.
Note If no PWM on HS1 and HS2 is required, the PWMIN
terminal must be connected to the VDD terminal.
LIN-PU—LIN Pull-UP Enable Bit
This bit controls the LIN pull-up resistor during SLEEP and
STOP modes.
1 = Pull-up disconnected in SLEEP and STOP modes.
0 = Pull-up connected in SLEEP and STOP modes.
Note This bit is only available on the final product. All
versions before MC-Qualification will not include this function.
LINSL1 and LINSL2—LIN Baud Rate and Low-Power Mode
Selection Bits
These bits select the LIN slew rate and requested low-power
mode in accordance with Table 6. Reset clears the LINSL1 and
LINSL2 bits.
Table 6. LIN Baud Rate and Low-Power Mode
Selection Bits
L1—Input L1 Status Flag Bit
This flag reflects the status of the L1 input terminal and
indicates the wake-up source.
1 = L1 input high or wake-up by L1 (first register read after
wake-up indicated with INT SOURCE = 1).
0 = L1 input low.
L2—Input L2 Status Flag Bit
This flag reflects the status of the L2 input terminal and
indicates the wake-up source.
1 = L2 input high or wake-up by L2 (first register read after
wake-up indicated with INT SOURCE = 1).
0 = L2 input low.
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.
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.
VSUV/BATFAIL—Undervoltage Status Flag Bit
This flag is set on a VSUP undervoltage condition.
1 = Undervoltage detected. VSUP below 6.0 V
0 = No undervoltage detected. VSUP above 6.0 V.
VSOV—Overvoltage Status Flag Bit
This flag is set on a VSUP overvoltage condition.
1 = Overvoltage detected, VSUP above 19 V.
0 = No overvoltage detected, VSUP below 18 V.
LINWU/LINFAIL—LIN Status Flag Bit
This bit indicates a LIN wake-up condition.
1 = LIN bus wake-up occurred or LIN over- current/
temperature occurred.
0 = No LIN bus wake-up occurred.
INT SOURCE—Register Content Flags or Interrupt
This bit indicates if the register contents reflect the flags or
the wake-up source.
1 = SPI word reflects the interrupt or wake-up source.
0 = No interrupt occurred. Other SPI bits report real time
status.
