Description
Port V general purpose input/output data—Data Register, Motor driver PWM output, MOSI of SPI, PWM channel
5
Port V pin 1 is associated with the Motor PWM output, SPI and PWM channel 6.
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 5, IIC and general purpose I/O function
• The Motor driver PWM takes precedence over the SPI, PWM channel 5 and general purpose I/O function.
• The MOSI of SPI takes precedence over the PWM channel 5 and the general purpose I/O function
• The PWM channel 5 takes precedence over the general purpose I/O function

Port V general purpose input/output data—Data Register, Motor driver PWM output, TIM1 channel 0, MISO of
PTV SPI, PWM channel 4, SCL of IIC
Port V pin 0 is associated with the Motor PWM output, TIM1 channel 0, SPI and PWM channel 5 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, TIM0, TIM1, SPI, PWM channel 4, IIC and general purpose
I/O function
• The Motor driver PWM takes precedence over the TIM0, TIM1, SPI, PWM channel 4, IIC and general purpose I/O
function.
• The TIM0 output compare function take precedence over the TIM1, SPI, PWM channel 4, IIC and general purpose
I/O function.
• The TIM1 output compare function take precedence over the SPI, PWM channel4, IIC and general purpose I/O¹
• The SCL of IIC takes presentees over the PWM channel 4, SPI and general purpose I/O function
• The PWM channel 4 takes precedence over the SPI and the general purpose I/O function
• The MISO of SPI takes precedence over the general purpose I/O function
1 _{In order TIM1 input capture to be function correctly, need to disable all the output functions on the corresponding channel. Also}
the corresponding SRRV bit should be set to 0.
