All versions of the SimpleLink CC13xx and CC26xx microcontrollers from Texas
Instruments include internal flash. The cc26xx flash driver supports both the
CC13xx and CC26xx family of devices. The driver automatically recognizes the
-specific version's flash parameters and autoconfigures itself. Flash bank 0
+specific version's flash parameters and autoconfigures itself. The flash bank
starts at address 0.
