LIN
Two D-type 9-pin LIN connectors CN11 (LIN1) and CN14 (LIN2) are available on the
STM8A/128-EVAL evaluation board. The LIN1 connector is connected to channel 4 of the
multiplexer U17, while the LIN2 connector is connected to channel 0 of the multiplexer U18.
Either master or slave operation mode is supported by both LIN connectors and can be
selected by setting jumpers JP11 and JP12. The LIN1 and LIN2 transceivers are powered
by an external voltage from 6 V to 26 V connected to pin 9 of the LIN DB9 connector.
Table 6.
Motor control
The STM8A/128-EVAL evaluation board supports inductor motor control via a 34-pin
connector CN10, which provides all required control and feedback signals to and from the
motor power-driving board. Available signals on this connector include emergency stop,
motor speed, 3-phase motor current, bus voltage, heatsink temperature coming from the
motor driving board and 6 channels of PWM control signals going to the motor driving
circuit.
Either PFC_PWM or Dissipative_Brake signal can be enabled by setting jumper JP13.

Motor control related configuration
LIN1 operates in master mode when JP11 is set as shown:
This is the default setting.
LIN1 operates in slave mode when JP11 is set as shown:
LIN2 operates in master mode when JP12 is set as shown:
LIN2 operates in slave mode when JP12 is set as shown:
This is the default setting.
PFC_PWM signal is enabled and connected to PD0 when JP13
is set as shown:
This is the default setting.
Dissipative_Brake signal is enabled and connected to PD0 when
JP13 is set as shown:
JP9 should be kept open when encoder signal is from pin 31 of CN10 while it
should be kept closed when analog signal is from pin 31 of CN10 for special
motor.
Default setting: not fitted
This 47 kΩ must be removed from the board to enable encoder phase A feature
for motor control applications. The location of this resistor is indicated in
