  This demo is based on the GD32G553Q-EVAL-V1.0 board, it shows how to configure the
TIMER peripheral update interrupt with the corresponding interrupt request to generate
a time base.

  The frequency of TIMER5 is set to 216MHz, the prescaler is 10800, so TIMER5 counter
frequency is 20KHz. TIMER5 CARL is 20000, so the period is 1s (20000 / 20000 = 1s).

  Enable the update interrupt, so the TIMER5 generates an interrupt each 1s, in the
handler routine, LED2 is toggled each 1s.
