15.1
The H8S/2350 Group incorporates a successive approximation type 10-bit A/D converter that
allows up to eight analog input channels to be selected.
15.1.1
A/D converter features are listed below
10-bit resolution
Eight input channels
Settable analog conversion voltage range
High-speed conversion
Choice of single mode or scan mode
Four data registers
Sample and hold function
Three kinds of conversion start
A/D conversion end interrupt generation
Module stop mode can be set
Conversion of analog voltages with the reference voltage pin (V
voltage
Minimum conversion time: 6.7 µs per channel (at 20-MHz operation)
Single mode: Single-channel A/D conversion
Scan mode:
Conversion results are held in a 16-bit data register for each channel
Choice of software or timer conversion start trigger (TPU), or ADTRG pin
A/D conversion end interrupt (ADI) request can be generated at the end of A/D conversion
As the initial setting, A/D converter operation is halted. Register access is enabled by
exiting module stop mode.
