RECEIVER OUTPUT PIN (RXD)
the LIN interface and reports the state of the bus voltage:
RXD Low when LIN bus is dominant, RXD High when LIN bus
is recessive.
TRANSMITTER INPUT PIN (TXD)
the LIN interface and controls the state of the bus output
(dominant when TXD is Low, recessive when TXD is High).

communicates using a single wire. This enables this device
to be compatible with 3-wire bus systems, where one wire is
used for communication, one for battery, and one for ground.
MASTER OUT SLAVE IN PIN (MOSI)
data input is sampled on the negative edge of SCLK.
MASTER IN SLAVE OUT PIN (MISO)
digital tri-state output used to shift serial data to the
microcontroller. Data on this output pin changes on the
positive edge of the SCLK. When CS is High, this pin will
remain in the high-impedance state.
CHIP SELECT PIN (CS)
a valid SPI communication and allow for several devices to
be connected in the same SPI bus without contention. A
rising edge on CS signals the end of the transmission and the
moment the data shifted in is latched. A valid transmission
must consist of 8 bits only.

Analog Multiplexer, including the VSENSE and L1 input
voltages, and the internal junction temperature.
