8255 Programmable Peripheral Interface - UPB
Data Bus Buffer. This 3-stable bi-directional 8-bit buffer is used to interface the 8255A to the systems data bus. Data is transmitted or received by the buffer upon execution of input or output instructions by the CPU. Control words and status information are also transferred through the data bus buffer.
Introduction to 8255A PPI (Programmable Peripheral Interface)
Figure (b) shows all the functions of 8255A, classifying according to two modes: the Bit Set-Reset (BSR) mode and Input Output (I/O) mode. The BSR mode is used to set or reset the bits in port C. The I/O mode is further divided into three modes: mode 0, mode 1 and mode 2.

Draw & explain block diagram of 8259 PIC. - Ques10
Fig below shows the internal block diagram of the 8259A. It includes eight blocks: data bus buffer, read/write logic, control logic, three registers (IRR, ISR and IMR), priority resolver, and cascade buffer. Data Bus Buffer: The data bus buffer allows the 8085 to send control words to the 8259A and read a status word from the 8259A. The 8•bit
