Function and settings
Selects PD7 (Analog Comparator Positive Input 0)
J22 pin 1 & 2 connected – PD7 (ACMP0) is connected to the hall sensor output 1. (default
configuration) (Sensor mode)
J22 pin 2 & 3 connected – PD7 (ACMP0) is connected to the filtered U_motor signal.
(Sensorless mode)
Selects PB5 (Analog Comparator Negative Input 1) ) (Sensorless mode)
J23 pin 1 & 2 connected – PB5 (ACMN1) is connected to the Vneutral point in sensorless
mode : filtered Vn_motor signal.
J23 pin 2 & 3 connected – PB5 (ACMN1) is connected to the filtered V_motor signal in
sensorless mode.
Selects PC6 (Analog Comparator Positive Input 1)
J24 pin 1 & 2 connected – PD7 (ACMP1) is connected to the hall sensor output 2. (default
configuration) (Sensor mode)
J24 pin 2 & 3 connected – PD7 (ACMP1) is connected to the filtered V_motor signal.
(Sensorless mode)
Selects PD6 (Analog Comparator Negative Input 2)
J25 pin 1 & 2 connected – PD6 (ACMN2) is connected to the Vneutral point: filtered
Vn_motor signal. (Field Oriented Control mode)
J25 pin 2 & 3 connected – PD6 (ACMN2) is connected to the filtered W_motor signal.
(Sensorless mode)
Selects PD5 (Analog Comparator Positive Input 2)
J26 pin 1 & 2 connected – PD5 (ACMP2) is connected to the hall sensor output 3 (default
configuration) (Sensor mode)
J26 pin 2 & 3 connected – PD5 (ACMP2) is connected to the filtered W_motor signal.
(Sensorless mode)
Selects voltage source UVCC (Power supply for USB stage)
When working at Vcc 2.7V-3.3V, the user can keep the USB functional by selecting power
supply for USB coming from VBUS rather than from Vcc.
J28 open
J28 pin 1 & 2 connected – UVCC connected to Vcc coming from Power board (Default
configuration)
J28 pin 2 & 3 connected – UVCC connected to Vbus coming from USB line
– UVCC not connected, USB bridge not usable
