MPS6525 Description
v -'-'modore aamicanduct;or group ~~@@ 6525 TRI·PORT INTERFACE MPS 6525 TRI-PORT INTERFACE CONCEPT ... The 6525 TRI·PORT Interface (TPI) is designed to simplify the implementation of plex I/O operations in microputer systems. It bines two dedicated a·bit 110 ports with a third a-bit port programmable for either normal 110 operation or priority interrupt/handshaking control.
