SPI REGISTER OVERVIEW
Table 7 summarizes the SPI Register bit meaning, reset
value, and bit reset condition.
.
SPI Control Register (Write)
Table 8 shows the SPI Control register bits by name.
LINSL2:1—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 9. Reset clears the
LINSL2:1 bits.
LIN-PU—LIN Pullup Enable Bit
This bit controls the LIN pullup resistor during Sleep and
Stop modes.
1 = Pullup disconnected in Sleep and Stop modes.
0 = Pullup connected in Sleep and Stop modes.
HS3ON:HS1ON—High-Side H3:HS1 Enable Bits
These bits enable the HSx. Reset clears the HSxON 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.
MODE2:1—Mode Section Bits
The MODE2:1 bits control the operating modes and the
watchdog in accordance with Table 10.
To safely enter Sleep or Stop mode and to ensure that
these modes are not affected by noise issue during SPI
transmission, the Sleep/Stop commands require two SPI
transmissions.

30.
D7 signals interrupts and wake-up interrupts, D6:D0 indicated the source.
31.
The first SPI read after reset returns the BATFAIL flag state on bit D4.
