The W7500 embedded Flash memory can be programmed using in-application programming.
IAP allows the user to re-program the Flash memory while the application is running. The
program and erase operations can be performed over the whole product voltage range.
In
W7500x_Library_Examples(https://github.com/Wiznet/W7500/tree/master/W7500x_Library
_Examples/Projects/Peripheral_Examples/Flash/IAP_Example), there is the IAP Example
Project and the below function is supported to use IAP.
void DO_IAP( uint32_t id, uint32_t dst_addr, uint8_t* src_addr, uint32_t size);
This function requests those parameters, id, dst_addr, src_addr and size. 'id' is already defined
in 'main.c'. 'dst_addr' is the flash memory address in the upper table. 'src_addr' is the buffer
pointer user want to program. 'size' is the flash size user chooses. Please refer flash address
and size mentioned in the upper table.
