| Baseline value for RXFIFO size computation |
| |
| The OTG_FS and OTG_HS USB controllers use a single "RxFIFO" to hold |
| data received by all OUT endpoints. The RxFIFO's size is influenced |
| by various parameters: the optimal value depends on the exact USB |
| configuration that will be used, which the driver does not know by |
| the time it has to configure the RxFIFO size. |
| |
| The total RxFIFO size will be equal to the value of this option |
| plus a fixed overhead that the driver can derive from the hardware |
| configuration (e.g., number of endpoints implemented). |
| |
| Refer to STM32 Reference Manuals for more details about the RxFIFO. |
