7
TF2
Timer 2 Overflow Flag. Set by a Timer 2 overflow, and must be cleared by software. TF2
will not be set when either (RCLK, RCLK1)=1 or (TCLK, TCLK)=1
6
EXF2
Timer 2 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
5
RCLK
(1)
Receive Clock Flag (UART 1). When set, causes the serial port to use Timer 2 overflow
pulses for its receive clock in Modes 1 and 3. TCLK=0 causes Timer 1 overflow to be
used for the receive clock
4
TCLK
(1)
Transmit Clock Flag (UART 1). When set, causes the serial port to use Timer 2 overflow
pulses for its transmit clock in Modes 1 and 3. TCLK=0 causes Timer 1 overflow to be
used for the transmit clock
3
EXEN2
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 Time 2 to ignore events at T2EX
2
TR2
Start/stop control for Timer 2. A logic 1 starts the timer
1
C/T2
Timer or Counter Select for Timer 2. Cleared for timer operation (input from internal
system clock, t
CPU
); set for external event counter operation (negative edge triggered)
0
CP/RL2
Capture/Reload Flag. When set, capture will occur on negative transition of T2EX if
EXEN2=1. When cleared, auto-reload will occur either with TImer 2 overflows, or
negative transitions of T2EX when EXEN2=1. When either (RCLK, RCLK1)=1 or (TCLK,
TCLK)=1, this bit is ignored, and timer is forced to auto-reload on Timer 2 overflow
