80C51 with 1 kB RAM, SPI
6.5.1 Capture mode
In the Capture mode there are two options which are selected by bit EXEN2 in T2CON. If
EXEN2 = 0 Timer 2 is a 16-bit timer or counter (as selected by C/T2 in T2CON) which
upon overowing sets bit TF2, the Timer 2 overow bit. The Capture mode is illustrated in
This bit can be used to generate an interrupt (by enabling the Timer 2 interrupt bit ET2 in
the IE register). If EXEN2 = 1, Timer 2 operates as described above, but with the added
feature that a 1-to-0 transition at external input T2EX causes the current value in the
Timer 2 registers, TL2 and TH2, to be captured into registers RCAP2L and RCAP2H,
respectively.
In addition, the transition at T2EX causes bit EXF2 in T2CON to be set, and EXF2 like
TF2 can generate an interrupt (which vectors to the same location as Timer 2 overow
interrupt). The Timer 2 interrupt service routine can interrogate TF2 and EXF2 to
determine which event caused the interrupt.
4
TCLK
Transmit clock ag. When set, causes the UART to use Timer 2 overow
pulses for its transmit clock in modes 1 and 3. TCLK = 0 causes Timer 1
overows to be used for the transmit clock.
3
EXEN2
Timer 2 external enable ag. 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.
2
TR2
Start/stop control for Timer 2. A logic 1 enables the timer to run.
1C/T2
Timer or counter select. (Timer 2)
0 = internal timer (fosc /6)
1 = external event counter (falling edge triggered; external clock’s
maximum rate = fosc / 12)
0
CP/RL2
Capture/Reload ag. When set, captures will occur on negative transitions
at T2EX if EXEN2 = 1. When cleared, auto-reloads will occur either with
Timer 2 overows or negative transitions at T2EX when EXEN2 = 1. When
either RCLK = 1 or TCLK = 1, this bit is ignored and the timer is forced to
auto-reload on Timer 2 overow.
