TRI-PORT
INTERFACE
CONCEPT ...
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.
FEATURES:
• 24 individually programmable 110 lines or
16 110 lines, 2 handshake lines and 5 in-
terrupt inputs.
• Priority or non-priority interrupts
• Automatic handshaking
• Completely static operation
• Two TTL Drive Capabi Iity
• a directly addressable registers
• 1 MHz, 2MHz and 3MHz operation
