22.3 Waveform Generating Function

Waveforms are generated when the value of the base timer matches that of the G1POj register (j=0 to 7).

The waveform generating function has the following three modes :

• Single-phase waveform output mode

• Phase-delayed waveform output mode

• Set/Reset waveform output (SR waveform output) mode

Table 22.7 lists pin settings of the waveform generating function. Table 22.8 lists registers associated with

the waveform generating function.

Function

G1POCRj

MOD2 to MOD0

Select waveform output mode

IVL

Select default output value

RLD

Select a timing to reload the value of the G1POj register

INV

Select if output level is inversed

G1POj

Select when output waveform is inversed
