Description
Port V general purpose input/output data—Data Register, Motor driver PWM output, SS of SPI, PWM channel 7,
SDA of IIC
Port V pin 3 is associated with the Motor PWM output, SPI and PWM channel 4 and IIC.
When not used with the alternative functions, this pin can be used as general purpose I/O. If the associated data
direction bit of this pins is set to 1, a read returns the value of the port register, otherwise the buffered pin input state
is read.
• The SSD takes precedence over the Motor Driver, SPI, PWM channel 7, IIC and general purpose I/O function
• The Motor driver PWM takes precedence over the SPI, PWM channel 7, IIC and general purpose I/O function.
• The SDA of IIC takes precedence over the PWM channel 7, SPI and general purpose I/O function
• The PWM channel 7 takes precedence over the SPI and general purpose I/O function
• The SS of SPI takes precedence over the general purpose I/O function

PTV PWM channel 6
Port V pin 2 is associated with the Motor PWM output, SPI and PWM channel 7.
When not used with the alternative functions, this pin can be used as general purpose I/O. If the associated data
direction bit of this pins is set to 1, a read returns the value of the port register, otherwise the buffered pin input state
is read.
• The SSD takes precedence over the Motor Driver, TIM0, TIM1, SPI, PWM channel 6, IIC and general purpose
I/O function
• The Motor driver PWM takes precedence over the TIM0,TIM1, SPI, PWM channel 6 and general purpose I/O
function.
• The TIM0 channel 5 output function takes precedence over the TIM1, SPI, PWM channel 6 and general purpose
I/O function.
• The TIM1 channel 1 output function takes precedence over the SPI, PWM channels 6 and the general purpose
I/O function if related channel is enabled¹
• The SCK of SPI takes precedence over the PWM channel 6 and the general purpose I/O function
• The PWM channel 6 takes precedence over the general purpose I/O function
