Analog-to-Digital Converter (ATD)
16.2 Introduction
The analog-to-digital converter (ATD) is an 8-channel, 8-bit,
multiplexed-input, successive-approximation analog-to-digital
converter, accurate to ±1 least significant bit (LSB). It does not require
external sample and hold circuits because of the type of charge
redistribution technique used. The ATD converter timing can be
synchronized to the system P-clock. The ATD module consists of a
16-word (32-byte) memory-mapped control register block used for
control, testing and configuration.
16.3 Features
Features of the ATD module include:
• Eight multiplexed input channels
• Multiplexed-input successive approximation
• 8-bit resolution
• Single or continuous conversion
• Conversion complete flag with CPU interrupt request
• Selectable ATD clock
