Part Number: UCD3138
it's said that FIRMWARE_START – Ramp start bit, self-clearing by ramp logic; so every time we update a new value to FeCtrl0Regs.RAMPDACEND.bit.RAMP_DAC_VALUE, we need to set RAMPCTRL's FIRMWARE_START to 1 to start the DAC ramp, right?
is there any side effect if we update FeCtrl0Regs.RAMPDACEND.bit.RAMP_DAC_VALUE frequently before ramp ends?
thanks a lot;

Yes. You need to set FIRMWARE_START =1 to initialize a new ramping. It is preferred to initialize a new RAMP_DAC_VALUE after the old one is finished.
