Equations for 11-bit PWM Generator

PWM Frequency FPWM = F clock source ÷ [ P × (CB10_1 + 1) ]

PWM Duty(in time) = (1 / FPWM) × ( DB10_1 + DB0 × 0.5 + 0.5) ÷ (CB10_1 + 1)

PWM Duty(in percentage) = ( DB10_1 + DB0 × 0.5 + 0.5) ÷ (CB10_1 + 1) × 100%

Where,

P=PWMGCLK[6:4]; pre-scalar P=1,2,4,8,16,32,64,128

DB10_1 = Duty_Bound[10:1] = {PWMGxDTH[7:0], PWMGxDTL[7:6]},

duty bound

DB0 = Duty_Bound[0] = PWMGxDTL[5]

CB10_1 = Counter_Bound[10:1] = {PWMGCUBH[7:0], PWMGCUBL[7:6]},

counter bound

Time

0x7FF

Duty[10:0]
