![]() ![]() This memory can also be accessed by the standard data bus using a 0x20 address offset in the access command. The IN/OUT data bus has direct access to the 64-byte I/O Memory section (not Extended) using a 0x00 to 0x1F address. For the Extended I/O space from 0圆0 – 0xFF in SRAM, only the ST/STS/STD (Store) and LD/LDS/LDD (Load) instructions can be used. The ATmega328P is a complex microcontroller with more peripheral units than can be supported within the 64 locations reserved in the Opcode for the IN and OUT instructions. These support endless possible applications for this small and affordable package. ![]() A wide range of flexible I/O options includes I2C, SPI, and uniquely Programmable I/O (PIO).
