PULSE OUTPUT PORT MODE
9.1 Overview
9.1 Overview
The pulse output port mode function is used to change the output levels at several pins simultaneously with
the following: each underflow occurrence in timer A or each valid edge input of an external signal. The pulse
output port mode has two operation modes as listed in Table 9.1.1.
