Active quench, recharge and gate timing control for single-photon avalanche diodes with hold-off and afterpulse suppression.
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.

| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| spad | inout | analog | 8 | |
| click_out | out | parallel | 8 |
