Description
Port V general purpose input/output data—Data Register, Motor driver PWM output
Port V pins are associated with the Motor PWM output.
When not used with the alternative functions, these pins can be used as general purpose I/O. If the associated data
direction bits of these pins are 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 and general purpose I/O function
• The Motor driver PWM takes precedence over the general purpose I/O function.
Port V general purpose input/output data—Data Register, Motor driver PWM output, TIM1 channel 3,2
Port V pins are associated with the Motor PWM output and TIM1 channels 3-2
When not used with the alternative functions, these pins can be used as general purpose I/O. If the associated data
direction bits of these pins are 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 and TIM0,TIM1 and general purpose I/O function
• The Motor driver PWM takes precedence over the TIM0, TIM1 and the general purpose I/O function.
• The TIM0 output compare function takes precedence over the TIM1 and the general purpose I/O function.
• The TIM1 output compare function takes precedence over the general purpose I/O function if the related channels
is enabled¹
