Part Number: UCD3138

Tool/software: Code Composer Studio

I use a UCD3138RGC(64pin).

I use the following address code.

www.ti.com/.../UCD3138FW-PSFB (UCD3138 Phase Shift Full Bridge Firmware)

The following is described in Section 11.12 of the Technical Reference manual.

"The C code below should provide an approximate 10 KHz interrupt from the T16:
TimerRegs.T16PWM0CMP0DAT.bit.CMP_DAT = 1587; //value to reset counter "

Please tell me the frequency of T16 counter.

Hi,

Setting of TimerRegs.T16PWM0CMP0DAT.bit.CMP_DAT = 1587; will provide an (15625KHz/1587= 9.85 KHz) interrupt rate (approximate of 10 Khz ).

As the Clock to the timer is of 15.625 MHz.

Regards,
