Document Summary

I/o hardware: port integration module (pim, bidirectional i/o ports, built-in i/o devices, i/o interface to external devices. Pim: implements the interface between the internal i/o devices and the i/o pins. Dual roles: most i/o ports can be. Serial io vs parallel io: serial io. Data transmission/reception one bit at a time. Spi (synchronous peripheral interface: parallel io. This class will refer this when discussing about parallel io. Bidirectional io port (referring to parallel io ports: unidirectional ports (unidirectional arrow for pins pe0, pe1) Port a and port b in expanded chip mode. Bidirectional io port logic (image: everything inside dotted-line correspond to each bit, internal address bus [2] Checks given address to the address of the port and see if it"s true. If true, the address decoder [3] will set the respective port addresses to true: r/w_l control signal [5]
