93 / 166 page  ST7265x 93/166 PWM/BRM GENERATOR (Cont’d) PWM/BRM Outputs The PWM/BRM outputs are assigned to dedicated pins. The PWM/BRM outputs can be connected to an RC filter (see Figure 53 for an example). The RC filter time must be higher than TCPUx64. Figure 53. Typical PWM Output Filter Table 29. 6-Bit PWM Ripple After Filtering With RC filter (R=1K Ω), fCPU = 8 MHz V DD = 5V PWM Duty Cycle 50% R=Rext Note: after a reset these pins are tied low by de- fault and are not in a high impedance state.
