Figure 7.5 Extended Interrupts and Wake Events
Note: Wake events apply per pin and are available to all functions of that pin. For example, if the
RXD function is selected as an alternate function of the GPIO8 pin (MISC7 = 1), the WK_SE12
event can be used for IR wake-up. See Section 12.3, "Wake-Up Events".
