Function
Enables or disables the A/D converter interrupt.
If EADC = 0, the A/D converter interrupt is disabled.
Enables or disables external interrupt 2/capture/compare interrupt 4.
If EX2 = 0, external interrupt 2 is disabled.
Enables or disables external interrupt 3/capture/compare interrupt 0.
If EX3 = 0, external interrupt 3 is disabled.
Enables or disables external interrupt 4/capture/compare interrupt 1.
If EX4 = 0, external interrupt 4 is disabled.
Enables or disables external interrupt 5/capture/compare interrupt 2.
If EX5 = 0, external interrupt 5 is disabled.
Enables or disables external interrupt 6/capture/compare interrupt 3.
If EX6 = 0, external interrupt 6 is disabled.
Exables or disables the timer 2 external reload interrupt.
EXEN2 = 0 disables the timer 2 external reload interrupt.
The external reload function is not affected by EXEN2.
This bit is not used for interrupt control.
