Peripheral highlights
• Support for simultaneous and software triggering conversions
• Support for multi-triggering mode with a programmable number of conversions on
each trigger
• Each ADC has ability to scan and store up to 8 conversion results
1.6.3 Inter-Module Crossbar and AND-OR-INVERT logic
• Provides generalized connections between and among on-chip peripherals: ADCs,
12-bit DAC, Comparators, Quad Timers, eFlexPWMs, PDBs, EWM, Quadrature
Decoder, and select I/O pins
• User-defined input/output pins for all modules connected to crossbar
• DMA request and interrupt generation from crossbar
• Write-once protection for all registers
• AND-OR-INVERT function that provides a universal Boolean function generator
using a four-term sum-of-products expression, with each product term containing
true or complement values of the four selected inputs (A, B, C, D).

•
Full rail-to-rail comparison range
Support for high speed mode and low speed mode
Selectable input source includes external pins and internal DACs
Programmable output polarity
6-bit programmable DAC as voltage reference per comparator
Three programmable hysteresis levels
Selectable interrupt on rising edge, falling edge, or toggle of comparator output
1.6.5 12-bit Digital-to-Analog Converter
• 12-bit resolution
• Powerdown mode
• Automatic mode allows the DAC to automatically generate pre-programmed output
waveforms including square, triangle, and sawtooth waveforms for applications such
as slope compensation
• Programmable period, update rate, and range
• Output can be routed to an internal comparator, ADC, or optionally off chip
1.6.6 Quad Timer
• Four 16-bit up/down counters with programmable prescaler for each counter
