14. 10-bit A/D Converter
The A/D converter is the module that converts analog input voltages to a digital value.
Characteristics of A/D Converter
Minimum converting time : 5.6
s/channel
Sample & hold circuit is built-in.
Resolution : 10 bits
Selection can be made for analog input from 8 channels.
Initiation of DMA transfer by interruption is possible.
Initiation factor can be selected from software, external trigger (falling edge) or reload timer (rising edge) .
Block Diagram
Single conversion mode
: 1 channel is selected for conversion
Scan conversion mode
: Converts multiple number of consecutive channels.
Maximum 8 channels are programmable.
Consecutive conversion mode
: Repeatedly converts the specified channel.
Suspension / conversion mode : Suspends after converting 1 channel and waits until the next one is
started up (synchronization for starting conversion is possible)
