Figure 15-5. EPORT Port Data Register (EPDR)
Edge port interrupt enable bits enable EPORT interrupt requests. If a bit in EPIER is set,
EPORT generates an interrupt request when:
Clearing a bit in EPIER negates any interrupt request from the corresponding EPORT pin.
Reset clears EPIE7–EPIE1.
0 Interrupt requests from corresponding EPORT pin disabled
1 Interrupt requests from corresponding EPORT pin enabled
Reserved, should be cleared.
Edge port data bits. Data written to EPDR is stored in an internal register; if any pin of the
port is configured as an output, the bit stored for that pin is driven onto the pin. Reading
EDPR returns the data stored in the register. Reset sets EPD7–EPD1.
Reserved, should be cleared.
• The corresponding bit in the EPORT flag register (EPFR) is set or later becomes set.
• The corresponding pin level is low and the pin is configured for level-sensitive operation.
