Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: This function is valid only when the timer 1 count start synchronous circuit is selected (I10=“1”).
3: This function is valid only when the timer 3 count start synchronous circuit is selected (I20=“1”).
4: Port C output is invalid when CNTR1 input is selected for the timer 3 count source.
