SPI REGISTER OVERVIEW
Table 7
summarizes the SPI Register bit meaning, reset
value, and bit reset condition.
.
Table 7. SPI Register Overview
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 Bit
This bit enables the 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.
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.

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