A/D Converter
The A/D converter converts analog input voltages to digital values. The A/D converter has the following features.
Conversion time: Minimum of 8.167
s per channel (for a 12 MHz machine clock)
Uses RC-type successive approximation conversion with a sample and hold circuit.
10-bit resolution
Eight program-selectable analog input channels
Single conversion mode:
Selectively convert a one channel.
Scan conversion mode:
Continuously convert multiple channels. Maximum of 8 program-
selectable channels.
Continuous conversion mode: Repeatedly convert specified channels.
Stop conversion mode:
Convert one channel then halt until the next activation. (Enables
synchronization of the conversion start timing.)
An A/D conversion completion interrupt request to the CPU can be generated on the completion of A/D
conversion. This interrupt can activate I2OS to transfer the result of A/D conversion to memory and is suitable
for continuous operation.
Activation by software, external trigger (falling edge), or timer (rising edge) can be selected.
