J7 14-Pin UUT Control Connector
Notes for Table:
● IT : Input TTL level
● JA : Jump to a predefined address A Input. A low on this line will cause a jump to that address.
● OEN0-OEN3 : IOM generated Output Enables. A low on these lines specifies the I/O group currently enabled.
● OT : Output TTL level
● P : Power/GND
● SCLK, SDOUT, SDIN, SSYNC : Reserved, Should not be connected at any time
● XOE0-XOE3 : External Output Enable - input control for each I/O group. A low on these lines will disable the specific group output drivers.
