The type of communication interface used in the Flash plug-in is configured in the BSLPLUGINCFG.PLUGINTYPE field in BSL configuration memory (see the technical reference manual in GUID-B9D85FB4-58FA-49A6-B348-0AAC807C61CF.html).
If the plug-in type has any of the ROM interface types (UART or I2C), the flash plug-in overrides the ROM implementation. If the type has a new type that is not available in ROM (for example, SPI), the plug-in is added as a new interface.
No. | Interface | Plug-in Type |
---|---|---|
1 | UART | 0x1000 |
2 | I2C | 0x2000 |
3 | Any other interface | 0xXXXX |
As shown in #FIG_MFC_2HT_NVB, after checking the flash plug-in type, the updated interface list is used for auto detection. Even after flash plug-in registration the ROM interfaces can be used if those interfaces are not overridden.
