2.2.5 Comparator (CMP)

The device includes two high-speed comparators each with two 8-input multiplexers for

both the inverting and non-inverting inputs of the comparator. Each CMP input channel

connects to both muxes. Two of the channels are connected to internal sources, leaving

resources to support up to 6 input pins. See the channel assignment table for a summary

of CMP input connections for this device.

The CMPs also include one 6-bit DAC with a 64-tap resistor ladder network, which

provides a selectable voltage reference for applications where voltage reference is

needed for an internal connection to the CMP.

The CMPs can be optionally on in all modes except VLLS0.

2.2.6 12-bit DAC

The 12-bit digital-to-analog converter (DAC) is a low-power, general-purpose DAC.

The output of the DAC can be placed on an external pin or set as one of the inputs to

the analog comparator, op-amps, or ADC.

This device contains one 12-bit digital-to-analog converter (DAC) with programmable

reference generator output. The DAC includes a 16-word FIFO for DMA support.

2.2.7 Direct Memory Access Multiplexer (DMAMUX)

DMAMUX0 is a DMA request mux that allows up to 63 DMA request signals to be

mapped to any of the 8 DMA channels of DMA0. Because of the mux, there is no hard

correlation between any of the DMA request sources and a specific DMA channel.

Some of the modules support asynchronous DMA operation.

2.2.8 EMVSIM

The EMVSIM (Euro/Mastercard/Visa/SIM Serial Interface Module) is a standalone ISO

7816 module that is connected to the AIPS0 Peripheral Bridge. The EMVSIM module’s

clock source is the CPU/platform clock.
