For Syntek Semiconductor Co., Ltd. STK6011Px — Timer 2 (Standard Timer 2)
Simulation support for this peripheral or feature is comprised of:
- Dialog boxes which display and allow you to change peripheral configuration.
These simulation capabilities are described below.
Timer/Counter 2 Dialog
The Keil Debugger simulates all aspects of Timer/Counter 2. The
configuration is reflected in the Timer/Counter 2 Dialog that you may
open from the Peripherals Menu. You may use the controls in the
dialog to override the settings configured by your target program.
This allows you to learn how the timer/counter works by interactively
changing the configuration settings.
Mode settings select the size and auto-reload functions,
and select either Timer or Counter operation for Timer 2.
T2CON (Timer Control Register) holds the run/stop and
overflow flag for Timer 2.
T2 (Timer/Counter 2) holds the value of Timer/Counter
RCAP2 (Reload/Capture Timer 2) holds the 16-bit
reload/capture register value.
TR2 (Timer 2 Run Control) is set to turn Timer 2 on, and
reset to turn it off.
C/T2# (Counter/Timer Select) is set to configure Timer 2
as an external event counter, or reset to configure it as a
CP/RL2# (Capture/Reload Select) is set for capture mode,
and reset for reload mode. When either RCLK = 1 or TCLK = 1, this
bit is ignored.
EXEN2 (Timer 2 External Enable) is set to capture or
reload based on pin T2EX (P1.1). This bit is only meaningful if
Timer 2 is being used to clock the serial port.
TCLK (Transmit Clock Enable) is set to use Timer 2
overflow pulses for the transmit clock.
RCLK (Receive Clock Enable) is set to use Timer 2
overflow pulses for the receive clock.
T2EX (Timer 2 Capture/Reload Trigger) is an external
input (P1.1/AN1/T2EX) for up/down counting or triggering a timer 2
T2 Pin is an external input pin for counter
TF2 (Timer 2 Overflow Flag) is set when a Timer 2
EXF2 (Timer 2 External Flag) is set when an external
event on T2EX causes a capture or reload of Timer 2.
