general-purpose input/output (GPIO) multiplexer
Most of the peripheral signals are multiplexed with general-purpose I/O (GPIO) signals. This enables the user
to use a pin as GPIO if the peripheral signal or function is not used. On reset, all GPIO pins are configured as
inputs. The user can then individually program each pin for GPIO mode or Peripheral Signal mode. For specific
inputs, the user can also select the number of input qualification cycles. This is to filter unwanted noise glitches.
32-bit CPU-Timers (0, 1, 2)
CPU-Timers 0, 1, and 2 are identical 32-bit timers with presettable periods and with 16-bit clock prescaling. The
timers have a 32-bit count down register, which generates an interrupt when the counter reaches zero. The
counter is decremented at the CPU clock speed divided by the prescale value setting. When the counter
reaches zero, it is automatically reloaded with a 32-bit period value. CPU-Timers 1 and 2 are reserved for
Real-Time OS (RTOS) applications. CPU-Timer 2 is connected to INT14 of the CPU. CPU-Timer 1 can be
connected to INT13 of the CPU. CPU-Timer 0 is for general use and is connected to the PIE block.
motor control peripherals
The F2810 and F2812 support the following peripherals which, are used for controlling motors:
EV:
The event manager module includes general-purpose timers, full-compare/PWM units,
capture inputs (CAP) and quadrature-encoder pulse (QEP) circuits. Two such event
managers are provided which enable two three-phase motors to be driven or four two-phase
motors. The event managers on the F2810 and F2812 are compatible to the event managers
on the 240x devices (with some minor enhancements).
The ADC block is a 12-bit converter, single ended, 16-channels. It will contain two
sample-and-hold units for simultaneous sampling.
