Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:0 = ITiE (i=1 to 8).
Interrupt Enable Control
Bits.
If an ITiE bit is set, the corresponding interrupt is
generated when
– a rising edge occurs on the pin PA4/IT1 or PA5/
IT2 or PB4/IT5 or PB5/IT6
or
– a falling edge occurs on the pin PA6/IT3 or PA7/
IT4 or PB6/IT7 or PB7/IT8
No interrupt is generated elsewhere.
Note: Analog input must be disabled for interrupts
coming from port B.
