TR0
Timer 0 Run Control. This bit is set or cleared by software to turn timer/counter on
or off.
Interrupt 1 Edge Detect Flag: 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 inverse of the pin.
Interrupt 1 Type Control. Set/cleared by software to specify falling edge/ low level
triggered external inputs.
Interrupt 0 Edge Detect Flag. 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 inverse of the pin.
Interrupt 0 Type Control: Set/cleared by software to specify falling edge/ low level
triggered external inputs.

7
GATE
Gating control: When this bit is set, Timer/counter 1 is enabled only while the
INT1
pin is high and the TR1 control bit is set. When cleared, the
INT1
pin has no effect,
and Timer 1 is enabled whenever TR1 control bit is set.
6
T
C/
Timer or Counter Select: When clear, Timer 1 is incremented by the internal clock.
When set, the timer counts falling edges on the T1 pin.
5
M1
Timer 1 mode select bit 1. See table below.
4
M0
Timer 1 mode select bit 0. See table below.
3
GATE
Gating control: When this bit is set, Timer/counter 0 is enabled only while the
INT0
pin is high and the TR0 control bit is set. When cleared, the
INT0
pin has no effect,
and Timer 0 is enabled whenever TR0 control bit is set.
2
T
C/
Timer or Counter Select: When clear, Timer 0 is incremented by the internal clock.
When set, the timer counts falling edges on the T0 pin.
1
M1
Timer 0 mode select bit 1. See table below.
0
M0
Timer 0 mode select bit 0. See table below.
