Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: This function is valid only when the INT pin/timer 1 control is enabled (I10=“1”) and the timer 1 count start synchronous circuit is selected (W51=“1”).
3: This function is valid only when the INT pin/timer 1 control is enabled (I10=“1”).
