Analog-to-Digital Converter (ATD) Module
conversion to the mode control unit. For V
to set the sampled signal level within itself without relying on the S/H machine to deliver them.
The mode control unit organizes the conversion, specifies the input sample channel, and moves the digital
output data from the SAR register to the result register. The result register consists of a dual-port register.
The SAR register writes data into the register through one port while the module data bus reads data out
of the register through the other port.
14.3.2
The S/H machine accepts analog signals and stores them as capacitor charge on a storage node located in
the SAR machine. Only one sample can be held at a time so the S/H machine and the SAR machine can
not run concurrently even though they are independent machines.
various resistors and capacitors.
When the S/H machine is not sampling, it disables its own internal clocks.The input analog signals are
unipolar. The signals must fall within the potential range of V
required to perform special conversions (i.e., convert V
