Port R general purpose input/output data—Data Register, LCD segment driver output
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
Port R general purpose input/output data—Data Register, LCD segment driver output, SCL of IIC
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
Port R general purpose input/output data—Data Register, LCD segment driver output, SDA of IIC
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
Port R general purpose input/output data—Data Register, LCD segment driver output
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
Port R general purpose input/output data—Data Register, TIM1/TIM0 channels
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
• The LCD segment driver output takes precedence over the general purpose I/O function
• The LCD segment driver output takes precedence over the IIC and general purpose I/O function
• The IIC function takes over the general purpose I/O function
• The LCD segment driver output takes precedence over the IIC and general purpose I/O function
• The IIC function takes over the general purpose I/O function
• The LCD segment driver output takes precedence over the general purpose I/O function
• The TIM1/TIM0 output compare function takes precedence over the general purpose I/O function
