Function
Timer 2 overflow flag
Set by a Timer 2 overflow and must be cleared by software. If the Timer 2
interrupt is enabled, TF2 = 1 will cause an interrupt.
External interrupt 6 edge flag
Set by hardware when external interrupt edge was detected or when a
compare event occurred at P5.3/T2CC3/INT6. Cleared when the interrupt
is processed.
External interrupt 5 edge flag
Set by hardware when external interrupt edge was detected or when a
compare event occurred at P5.2/T2CC2/INT5. Cleared when the interrupt
is processed.
External interrupt 4 edge flag
Set by hardware when external interrupt edge was detected or when a
compare event occurred at P5.1/T2CC1/INT4. Cleared when the interrupt
is processed.
External interrupt 3 edge flag
Set by hardware when external interrupt edge was detected or when a
compare event occurred at P5.0/T2CC0/INT3. Cleared when the interrupt
is processed.
External interrupt 2 edge flag
Set by hardware when external interrupt edge was detected or when a
compare event occurred at P5.4/INT2. Cleared when the interrupt is
processed.
A/D Converter interrupt request flag
