Input/Output Pins – These are the general purpose bidirectional data pins. When used as outputs, each
may be independently latched, registered or tristated. They can also each assume one other control
function (OE, CLK and MUXsel as described in the text).
Test Output Enable pin – This pin tristates all I/O pins when a logic low is driven.
Active LOW Input Pin – Resets all I/O register outputs when LOW.
Input Pins – Dedicated clock input pins. Each pin can drive any or all I/O cell registers.
Input Pin – When HIGH, this pin enables the Boundary Scan Test and Programming Interface. When
LOW, this pin enables the Lattice ISP protocol for programming and tristates all I/O pins, except those
used for the programming interface.
Input/Input Pin – Serial data input during ISP programming or Boundary Scan mode.
Input/Input Pin – Serial data clock during ISP programming or Boundary Scan mode.
Input/Input Pin – Control input during ISP programming or Boundary Scan mode.
Output/Output Pin – Serial data output during ISP programming or Boundary Scan mode.
Ground (GND)
Vcc – Supply voltage (5V).
No Connect.
