16.3 OUTPUT SIGNALS ON PORT C
Different internal clock frequencies and PWM signals can be outout on all port C terminals. (PA[n] Output data)
•
The selection is done with the registers PC[n]OutSel1,0 . All clock outputs (PR1_x, PR2_x, ck_x) have a 50%
duty cycle.
•
By default the register data PCDOut[n] value is seleted as data output.
•
Data is only output if the corresponding PCOutEn[n] bit is high.
