Up to 6-channel, 10-bit analog-to-digital converter
Programmable polarity for transmitter and receiver
Active edge receive wake-up
Break detect and transmit collision detect supporting LIN
Internal connection to one SCI routable to external pins
— 8-/10-bit resolution
— 3 us, 10-bit single conversion time
— Left or right justified result data
— Internal oscillator for conversion in stop modes
— Wake up from low power modes on analog comparison > or <= match
— Continuous conversion mode
— Multiple channel scans
Pins can also be used as digital I/O
Up to 6 pins can be used as keyboard wake-up interrupt (KWI)
Internal voltages monitored with the ATD module
— V
VSENSE & VSUP pin low or a high voltage interrupt
VSENSE & VSUP pin can be routed via an internal divider to the internal ADC
Voltage regulator
— Linear voltage regulator directly supplied by VSUP (protected VBAT)
— Low-voltage detect with low-voltage interrupt on V
— Capable of supplying both the MCU internally and providing additional external current
— Over-temperature protection and interrupt
Internal Voltage regulator
— Linear voltage regulator with bandgap reference
— Low-voltage detect with low-voltage interrupt on VDDA
— Power-on reset (POR) circuit
— Low-voltage reset (LVR)
