1.4 Architecture Block Diagram

Note: Features in italics are NOT available in the 56F8122 device and are shaded in the following figures.

The 56F8322/56F8122 architecture is shown in Figure 1-1 and Figure1-2. Figure 1-1 illustrates how the

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

internal buses in the 56800E architecture and provides a br ief description of their function. Figure 1-2

shows 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.

Also shown in Figure 1-2 are connections between the PWM, Timer C and ADC blocks. These

connections allow the PWM and/or Timer C to control the timing of the start of ADC conversions. The

Timer C, Channel 2, output can generate periodic start (SYNC) signals to the ADC to start its conversions.

In another operating mode, the PWM load interrupt (SYNC output) signal is routed internally to the Timer

C, Channel 2, input as indicated. The timer can then be used to introduce a controllable delay before

generating its output signal. The timer output then triggers the ADC. To fully understand this interaction,

please see the 56F8300 Peripheral User Manual for clarifica tion on the operation of all three of these

peripherals.
