6.15.1 Block Diagram

The following analog subsystem block diagrams show the connections between the different integrated analog modules to the device pins. These pins fall into two categories: analog module inputs/outputs and reference pins.

The reference pins, VREFHI and VREFLO, can be used to supply an external voltage reference to the associated ADCs. VREFHI can also be used to supply the voltage reference to buffered DAC. The choice of reference is configurable per module for each CMPSS or buffered DAC; the selection is made using the module's configuration registers.

Some analog pins support digital functionality through muxed AIOs and AGPIOs. AIOs only support digital input functionality, while AGPIOs support full digital input and output functionality.

The following notes apply to all packages:

  • Not all analog pins are available on all devices. See the device data manual to determine which pins are available.
  • See the device data manual to determine the allowable voltage range for VREFHI and VREFLO.
  • An external capacitor is required on the VREFHI pins. See the device data manual for the specific value required.

Figure 6-32 shows the Analog Subsystem Block Diagram for the 128-/80-pin TQFP, the 64-pin LQFP, and the 56-pin VQFN.

Figure 6-33 shows the Analog Subsystem Block Diagram for the 100-pin LQFP.

Figure 6-34 shows the general overview of the analog group connections.

The analog pins and internal connections are given in Analog Pins and Internal Connections. Analog Signal Descriptions lists descriptions of analog signals.

Input connections to the CMPSS modules are selectable through a programmable input mux. Figure 6-34 demonstrates the connection between the input MUX of CMPSS modules, PGA modules, and ADC modules. Table 6-11 shows the mapping of ADC input signals and PGA input and output signals to CMPSS mux inputs.

  • To configure the CMPx_HP input mux for CMPSSx, write to the CMPxHPMXSEL field in the CMPHPMXSEL analog subsystem register.
  • To configure the CMPx_HN input mux for CMPSSx, write to the CMPxHNMXSEL field in the CMPHNMXSEL analog subsystem register.
  • To configure the CMPx_LP input mux for CMPSSx, write to the CMPxLPMXSEL field in the CMPLPMXSEL analog subsystem register.
  • To configure the CMPx_LN input mux for CMPSSx, write to the CMPxLNMXSEL field in the CMPLNMXSEL analog subsystem register.
