Timer_A and Timer_B
Two 16-bit timers, Timer A and Timer B, are available. They consist of a 16-bit
free-running counter driven by a programmable prescaler. Both timers feature
output compare, pulse width modulation (PWM) and input capture functions with
associated registers.
You
Free_when_not_run. If you choose the Frozen_when_not_run option, the
counter will run while the application runs, but when a breakpoint is encountered,
the counter will stop. If you choose the Free_when_not_run option, the counter
will continue to run even if a breakpoint is encountered.
The EXTCLK_A pin of the timer is not frozen when the program is stopped.
CSS (Clock Security System)
This option allows you to Enable or Disable the clock security system function
(CSS) which includes the clock filter and the backup safe oscillator. When enabled,
the selected OSCRANGE is used to determine the operating frequency range, and
when the frequency is out of range, the clock source will be switched to the backup
oscillator.
OSCRANGE
This option allows you to select the normal operating frequency range for the Clock
Security System (CSS). The following operating frequency range options are
available:
•
•
•
•
PLL
This option allows you to Enable or Disable the PLL which allows the multiplication
by two of the main input clock frequency. The PLL is guaranteed only when the
input frequency is between 2 and 4 MHz.
Refer to the datasheet of your target ST7 MCU for more information on the PLL.
