Example Name : SPMC75_TMR3_Demo B. Setup Procedure : Use the EVM demo board directly. C. Demo Judgement : 1. Connect the three phase hall sensor onto TIO0A, TIO0B and TIO0C. 2. Output the fetched hall sensor signal to port D. 3. Generate the active high type PWM waveform to TIO3A, TIO3B, TIO3C, TIO3D, TIO3E and TIO3F. D. Used Peripherals : 1. GPIO 2. TMR3 period interrupt with IRQ3. 3. The PWM carrier frequency is fixed at 4000 Hz and duty ratio remains at 12.5 %. E. Note : Do not montitor PWM waveform in ICE mode.
