Hi, I am trying to write to the CCU6_CC60SRH/L registers: CCU6_PAGE = 0x00; // switch to page 0 CCU6_CC60SRL |= 0x00; CCU6_CC60SRH |= 0x60; These registers allows me to change the duty cycle for my PWM signal. Writing with the above sequence does nothing. Using Infineon XC866 micro, Keil u3 toolset.
Hi Kobus, that is right. But as they are the shadow latches, you must enable shadow latch transfer to enable the update of the real registers. Stefan
Thank you, found it. CCU6_TCTR4L |= 0x40; // enable shadow transfer
