TF2
Timer 2 overflow flag
. Set by a Timer 2 overflow and must be cleared by software. TF2
will not be set when RTCLK = 1.
Timer 2 external flag.
Set when either a capture or reload is caused by a negative
transition on T2EX and when EXEN2 = 1. When Timer T2 interrupt is enabled,
EXF2 = 1 will cause the CPU to vector to Timer 2 interrupt routine. EXF2 must be
cleared by software.
General purpose flag
bit.
Receive/transmit clock flag
. When set, causes the UART serial port to use Timer 2
overflow pulses for its receive and transmit clock in Modes 1 and 3. RTCLK = 0 causes
Timer 1 overflows to be used for the receive and transmit clock.
Timer 2 external enable flag
. When set, allows a capture or reload to occur as a result
of a negative transition on T2EX, if Timer 2 is not being used to clock the serial port.
EXEN2 = 0, causes Timer 2 to ignore events at T2EX.
Start/stop control for Timer 2
. TR2 = 1 starts the timer.
Timer or counter select for Timer 2
. C/T2 = 0 selects the internal timer with a clock
frequency of
1
12
×
f
osc
. C/T2 = 1 selects the external event counter; negative edge
triggered.
Capture/Reload flag
. When set, captures will occur on negative transitions at T2EX, if
EXEN2 = 1. When cleared, auto-reloads will occur either with Timer 2 overflows or
negative transitions at T2EX when EXEN2 = 1. When RTCLK = 1, this bit is ignored and
the timer is forced to auto-reload on a Timer 2 overflow.
