S08 Calculating TPM bit resolution when used in PWM mode?

[iansmusical]

Hello Everyone,

Does anyone know how to calculate the TPM bit resolution when used in edge PWM mode please? For example, if I use a bus clock of 4MHz, a prescaler of 2 to generate a 120Hz period, I calculate TPMxMOD to be 16667 but how do I calculate the bit resolution of the PWM output?

Thanks in advance,

Ian

ln(16667)/ln(2) = 14.02
