EPIE[7:0] — Edge Port Interrupt Enable Bits
The read/write EPIE[7:0] bits enable EPORT interrupt requests. If a
bit in EPIER is set, EPORT generates an interrupt request when:
• The corresponding bit in the EPORT flag register (EPFR) is set
or later becomes set, or
• The corresponding pin level is low and the pin is configured for
level-sensitive operation
Clearing a bit in EPIER negates any interrupt request from the
corresponding EPORT pin. Reset clears EPIE[7:0].
1 = Interrupt requests from corresponding EPORT pin enabled
0 = Interrupt requests from corresponding EPORT pin disabled
