FUNCTION
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.
Interrupt 1 Edge Detect Flag: Set by hardware when an edge/level is detected on
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
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.
1: Set automatically when a power-on reset has occurred.

so program execution is frozen. But the clock to the serial, timer and interrupt
blocks is not stopped, and these blocks continue operating.
