The W7500 embedded Flash memory can be programmed using in-circuit programming or in-
application programming.
The in-circuit programming (ICP) method is used to update the entire contents of the Flash
memory using the SWD protocol or the boot loader to load the user application into the
microcontroller. ICP offers quick and efficient design iterations and eliminates unnecessary
package handling or socketing of devices.
In contrast to the ICP method, in-application programming (IAP) can use any communication
interface supported by the microcontroller (I/Os, UART, I
programming data into memory. IAP allows the user to re-program the Flash memory while
the application is running. Nevertheless, part of the application has to have been previously
programmed in the Flash memory using ICP.
The program and erase operations can be performed over the whole product voltage range.
They are managed through the following seven Flash registers:
Flash access control register (FACCR)
Flash address register (FADDR)
Flash data register (FDATAR)
Flash control register (FCTRLR)
