(3) 16-bit programmable pulse generation (PPG) output mode

Square wave pulse can be generated at any frequency and duty by timer 4. The

output pulse may be either low active or high active.

The PPG mode is obtained by inversion of the timer flip-flop TFF4 that is to be

enabled by the match of the up counter UC4 with the timer register TREG4 or TREG5

and to be output to TO4 (also used as P44). In this mode, the following conditions must

be satisfied.

< (Set value of TREG5)

Figure 3.8.10 Programmable Pulse Generation (PPG) Output Waveforms

When the double buffer of TREG4 is enabled in this mode, the value of register

buffer 4 will be shifted in TREG4 at match with TREG5. This feature makes easy the

handling of low duty waves.
