Programmed I/O Data Transfer scheme of 8085 microprocessor

Programmed I/O Data Transfer scheme of 8085 microprocessor is a simple parallel data transfer scheme. This method of data transfer is generally used in the simple microprocessor systems. It is obvious that where speed is unimportant. This method uses instructions to get the data into or out of the microprocessor. Programmed I/O Data Transfer scheme …

Memory mapped I/O interfacing with 8085 microprocessor

In memory mapped I/O interfacing with 8085 microprocessor, the I/O devices are not given separate addresses other than treated as a memory location. Whose address range between 0000h to FFFFh (64k).But some part of the space is reserved for I/O devices. The advantage is any instruction that references memory can also transfer data between an …
