Description of Changes
Initial version
Added reserved registers at the end the memory map.
Added following mention where applies:
(n conversion number, NOT channel number!)
Modified table “Analog Input Channel Select Coding” due to
new customer feature (SPECIAL17).
Updated document for 8 channels.
8.1 Introduction
The ADC12B8C is a 8-channel, 12-bit, multiplexed input successive approximation analog-to-digital
converter. Refer to device electrical specifications for ATD accuracy.
8.1.1 Features
• 8-, 10-, or 12-bit resolution.
• Conversion in Stop Mode using internally generated clock
• Automatic return to low power after conversion sequence
• Automatic compare with interrupt for higher than or less/equal than programmable value
• Programmable sample time.
• Left/right justified result data.
• External trigger control.
• Sequence complete interrupt.
• Analog input multiplexer for 8 analog input channels.
• Special conversions for V_RH, V_RL, (V_RL+V_RH)/2.
• 1-to-8 conversion sequence lengths.
