Peripheral ADC[edit | edit source]
The RZ/T2H SoC in the ZERO SOM has three units of a 12-bit A/D converter.
Description[edit | edit source]
The ADC12 module has the following features:
- 3 units: unit 0, 1 (4 channels in LLPP of Cortex-R52), unit 2 (15 channels in NONSAFETY)
- 12-bit digital value through successive approximation
- Three ways to start A/D conversion: Software trigger, timer (MTU3, ELC) trigger, external trigger
- Conversion time: 0.32 µs per channel
- Operating mode: Scan mode (single scan mode, continuous scan mode, or 3 group scan mode) and Group priority control
- Sample-and-hold function: Common sample-and-hold circuit included. In addition, channel-dedicated sample-and-hold function (3 channels: in all units) included
- Sampling time can be set up for each channel
- Double trigger mode (A/D conversion data duplicated)
- Event linking by the ELC
