TF1: Timer 1 overflow flag. Set by hardware on timer/counter overflow. cleared by hardware when
processor vectors to interrupt routine.
TR1: Timer 1 run control bit. Set/cleared by software to turn timer/counter on or off.
TF0: Timer 0 overflow flag. Set by hardware on timer/counter overflow. Cleared by hardware when
processor vectors to interrupt routine.
TR0: Timer 0 run control bit. Set/cleared by software to turn timer/counter on or off.
IE1: Interrupt 1 edge flag. Set by hardware when external interrupt edge detected. Cleared when
interrupt processed.
IT1: Interrupt 1 type control bit. Set/cleared by software to specify falling edge/low level triggered
external interrupt.
IE0: Interrupt 0 edge flag. Set by hardware when external interrupt edge detected. Cleared when
interrupt processed.
IT0: Interrupt 0 type control bit. Set/cleared by software to specify falling edge/low level triggered
external interrupt.

TF2:
Timer 2 overflow flag. Set by a Timer 2 overflow and must be cleared by software. TF2 will
not be set when RCLK = 1 or TCLK = 1.
Timer2 external flag. Set when either a capture or reload is caused by a negative transition
on T2EX and EXEN2 = 1. When Timer 2 interrupt is enabled, EXF2 = 1 will cause the CPU
to vector to the Timer 2 interrupt routine. EXF2 must be cleared by software.
Receive clock flag. RCLK = 1 causes the serial port to use Timer 2 overflow pulses for its
receive clock in mode 1 and 3. RCLK = 0 causes Timer 1 overflow to be used for the
EXF2:
RCLK:
receive
TCLK:
clock.
Transmit clock flag. TCLK = 1 causes the serial port to use Timer 2 overflow pulses for its
transmit clock in mode 1 and 3. TCLK = 0 causes Timer 1 overflow to be used for the
transmit clock.
EXEN2: Timer 2 external enable flag. EXEN2 = 1 allows a capture or reload to occur as a result of a
negative transition on T2EX if Timer 2 is not used to clock the serial port. EXEN2 = 0
causes
TR2:
TR2 = 1/0: turns on/off Timer 2.
C//T:
Timer or Counter select. Set 1/0 for external event counter (falling edge triggered) /inter
timer.
CP//RL2:Capture/reload flag.
Timer 2 to ignore events at T2EX.
