16-bit Digital Signal Controllers

Freescale Semiconductor 

Award-Winning Development Environment

This Digital Signal Controller also provides a full set of standard programmable peripherals that include

one Serial Communications Interface (SCI), one Serial Peripheral Interface (SPI), one Quad Timer, and

one Inter-Integrated Circuit (I2C) interface. Any of these interfaces can also be used as General Purpose

Input/Outputs (GPIOs).

1.3 Award-Winning Development Environment

Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use

component-based software application creation with an expert knowledge system.

The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation,

compiling, and debugging. A complete set of evaluation modules (EVMs), demonstration board kit and

development system cards will support concurrent engineering. Together, PE, CodeWarrior and EVMs

create a complete, scalable tools solution for easy, fast, and efficient development.

1.4 Architecture Block Diagram

The 56F8014’s architecture is shown in Figure 1-1, Figure 1-2, and Figure 1-3. Figure 1-1 illustrates

how the 56800E system buses communicate with internal memories and the IPBus Bridge. Figure 1-2 and

Figure 1-3 show the peripherals and control blocks connected to the IPBus Bridge. The figures do not

show the on-board regulator and power and ground signals. They also do not show the multiplexing

between peripherals or the dedicated GPIOs. Please see Part 2 Signal/Connection Descriptions to see

which signals are multiplexed with those of other peripherals.

1.4.1 PWM, TMR and ADC Connections

Figure 1-3 shows the over/under voltage connections from the ADC to the PWM and the connections to

the PWM from the TMR and GPIO. These signals can control the PWM outputs in a similar manner to the

over/under voltage control signals. See the 56F801X Peripheral Reference Manual for additional

information.

The PWM_reload_sync output can be connected to the TMR channel 3 input and the TMR channels 2 and

3 outputs are connected to the ADC sync inputs. TMR channel 3 output is connected to SYNC0 and TMR

channel 2 is connected to SYNC1. SYNC0 is the master ADC sync input that is used to trigger ADCA and

ADCB in sequence and parallel mode. SYNC1 is used to trigger ABCB in parallel independent mode.

These are controlled by bits in the SIM Control Register; see Section 6.3.1.
