Commodore 6525
The 6525 TRI·PORT Interface (TPI) is designed to simplify the implementation of complex I/O operations in microcomputer systems. It combines two dedicated a·bit 110 ports with a third a-bit port programmable for either normal 110 operation or priority interrupt/handshaking control. Depending on the mode selected, the 6525 can provide 24 individually programmable 110 lines or 16 110 lines, 2 handshake lines and 5 priority interrupt inputs.| Part No. | 6525 |
