LED driver plus photodiode TIA with ambient light cancellation and synchronized sampling for heart rate and SpO2 photoplethysmography.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
