6.6.2 Edge configuration register
Table 19.
This register works in combination with the level configuration register HILO (see
Table
The EDGE configuration register determines whether the event router responds to a level
change (EDGEn=1), or a constant level (EDGEn=0). The HILOn bit determines a
response to a rising edge (HILOn=1) or a falling edge (HILOn=0).
