IE1:
Interrupt 1 edge detect: Set by hardware when an edge/level is detected on
INT1
. This bit is
cleared by hardware when the service routine is vectored to only if the interrupt was edge
triggered. Otherwise it follows the pin.
Interrupt 1 type control: Set/cleared by software to specify falling edge/ low level triggered
external inputs.
IT1:
IE0:
Interrupt 0 edge detect: Set by hardware when an edge/level is detected on INT0 . This bit is
cleared by hardware when the service routine is vectored to only if the interrupt was edge
triggered. Otherwise it follows the pin.
Interrupt 0 type control: Set/cleared by software to specify falling edge/ low level triggered
external inputs.

GATE: Gating control: When this bit is set, Timer/counter x is enabled only while
INTx
pin is high
and TRx control bit is set. When cleared, Timer x is enabled whenever TRx control bit is set.

Timer or Counter Select: When cleared, the timer is incremented by internal clocks. When
set, the timer counts high-to-low edges of the Tx pin.
