Timer 1 overflow flag: This bit is set when Timer 1 overflows. It is cleared automatically when
the program does a timer 1 interrupt service routine. Software can also set or clear this bit.
Timer 1 run control: This bit is set or cleared by software to turn timer/counter on or off.
Timer 0 overflow flag: This bit is set when Timer 0 overflows. It is cleared automatically when
the program does a timer 0 interrupt service routine. Software can also set or clear this bit.
Timer 0 run control: This bit is set or cleared by software to turn timer/counter on or off.

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.
