PWM output

Billy — Sat, 18 Jan 2014 10:15:38 GMT

I am using MC9S08GT16ACFDE ( QFN-48 )

was trying to configure pin #20 ( TPM1CH0 ) as a PWM output ( variable duty ).

please advice how can I configure the MCU to do so ?

my initialization is below :

TPM1SC_TOIC = 1;

TPM1SC_CPWMS = 0;

TPM1SC_CLKSB = 1;

TPM1_C0SC_CH0F = 1;

TPM1_C0SC_MS0B = 1;

TPM1_C0SC_ELS0B = 1;

TPM1C1V = 0x0064;

TPM1MOD = 0x03E8;

something is wrong... I am not getting anything at pin #20... why ?
