impedance matching is really all about, why it s important in some situations and not important in others. Textbooks usually explain the idea of impedance matching with a very simple example of an electrical generator feeding a resistive load, as shown in Fig.1. Because the generator has an internal resistance
executed starting from address 0x0000, but the same memory area is addressed starting from 0x4000 when accessed via the data memory. Internal write operations to flash program memory have been disabled, and program memory, therefore, appears to firmware as read-only. Flash memory can only be written
