Analog-to-Digital (A/D) Converter
10.6 Channel Assignments
10.7 Single-Channel Operation
Technical Data
216
The multiplexer allows the A/D converter to select one of 16 analog
signals. Eight of these channels correspond to port E input lines to the
MCU, four of the channels are internal reference points or test functions,
and four channels are reserved. Refer to
The two types of single-channel operation are:
1. When SCAN = 0, the single selected channel is converted four
2. When SCAN = 1, conversions continue to be performed on the
consecutive times. The first result is stored in A/D result register 1
(ADR1), and the fourth result is stored in ADR4. After the fourth
conversion is complete, all conversion activity is halted until a new
conversion command is written to the ADCTL register.
selected channel with the fifth conversion being stored in register
ADR1 (overwriting the first conversion result), the sixth conversion
overwriting ADR2, and so on.
