Q2
The TMR0 interrupt is generated when the TMR0 register overflows from FFh to 00h. This
overflow sets bit T0IF (INTCON<2>). The interrupt can be masked by clearing bit T0IE
(INTCON<5>). Bit T0IF must be cleared in software by the Timer0 module interrupt service rou-
tine before re-enabling this interrupt. The TMR0 interrupt cannot awaken the processor from
SLEEP since the timer is shut-off during SLEEP. See
