EPF[7:0] — Edge Port Flag Bits
Reset:
Read:
Write:
When an EPORT pin is configured for edge triggering, its
corresponding read/write bit in EPFR indicates that the selected edge
has been detected. Reset clears EPF[7:0].
Bits in this register are set when the selected edge is detected on the
corresponding pin. A bit remains set until cleared by writing a 1 to it.
Writing 0 has no effect. If a pin is configured as level-sensitive
(EPPARx = 00), pin transitions do not affect this register.
