On STM32L4, a general-purpose timer has one counter, one ARR, but four CCRs (i.e., each
timer has four output channels, with one dedicated CCR for each channel). Which of the
following statement is FALSE?
a. Each timer can generate four outputs. However, these timer outputs have the same
period.
b. These four outputs can be left-edge-aligned, center-aligned, and right-edge-aligned,
determined by the timer counting mode and the timer output mode.
c. The output polarity (active high or active low) of each channel can be independently
programmed.
d. Each timer channel has its own dedicated interrupt handler
