Description
SB1
ON USB power through CN1 allowed (100 mA max)
OFF USB power through CN1 allowed (300 mA max)
SB2
ON STM8 forced in a Reset mode
OFF STM8 not forced in a Reset mode (standard operation)
SB3, SB4 (ST-LINK-UART)
ON
PA2 and PA3 on STM32F103CBT6 (ST-LINK MCU) are connected
respectively to PD5 and PD6 on STM8 to have UART virtual
communication enabled. Thus SB7 and SB9 must be OFF.
OFF
PA2 and PA3 on STM32F103CBT6 (ST-LINK MCU) are disconnected
from respectively PD5 and PD6 on STM8. PD5 and PD6 can be used
as GPIO on Arduino connector CN4.
SB5
ON
MCO on STM32F103CBT6 (ST-LINK MCU) is connected to PA1 on
STM8.
OFF
MCO on STM32F103CBT6 (ST-LINK MCU) is disconnected from
PA1 on STM8.
SB6
ON GND is connected to AGND.
OFF GND is not connected to AGND.
SB7, SB9
ON T_VCP_TX and T_VCP_RX are connected to CN3.
OFF T_VCP_TX and T_VCP_RX are disconnected from CN3.
SB8
ON
STM8 PD7 is connected to CN4 pin 5 for TLI support on
ARDUINO
®
Nano A7.
OFF
STM8 PD7 is disconnected to CN4 pin 5 for TLI support on ARDUINO
®
Nano A7.
SB10
ON
STM8 PF4 is connected to CN4 pin 5 for AI12 support on ARDUINO
®
Nano A7.
OFF
STM8 PF4 is disconnected from CN4 pin 5 for AI12 support on
ARDUINO
®
Nano A7.
SB11
ON
STM8 PF4 is connected to CN4 pin 6 for AI12 support on
ARDUINO
®
Nano A6.
OFF
STM8 PF4 is disconnected from CN4 pin 6 for AI12 support on
ARDUINO
®
Nano A6.
SB12
ON
STM8 PD7 is connected to CN4 pin 6 for TLI support on ARDUINO
®
Nano A6.
OFF
STM8 PD7 is disconnected from CN4 pin 6 for TLI support on
ARDUINO
®
Nano A6.
SB13
ON Output of voltage regulator LD39050PU33R is connected to 3.3V.
OFF Output of voltage regulator LD39050PU33R is not connected.
