Instruction
Connects the Crosspoint cell at the Input location
specified on the Address Register and the output
location specified in the Connect Serial instruction
(A6-A0).
All other connections from the same Input address or
the same Output address are set to no-connects.
NOTE: This instruction increments the Address
Register (Input address).
Connects the Crosspoint cell at the Input address
specified in the Address Register and the Output
address specified in the Connect instruction (A6-A0).
All connections to the same output address are set to
“no connect” while all other connections from the
same input remain the same as before.
Sets the 7-bit Address Register with the 7-bit address
(A6-A0) of the Instruction Register. The 7-bit address
of the Address Register becomes the Input port address
for Crosspoint Access.
Serialize the device ID and revision history out to
SDO. ID for the OCX1601 is 0x0000D89F
Resets the Crosspoint Array to no-connects. Sets the
Output buffer to Flow-through mode with Output
Enabled. The device ID is serialized to SDO.
Sets the RCE bit of the Mode Control Register with the
Serial instruction bit A0.
To turn ON the RCE bit, encode bit A0 to 1.
To turn OFF the RCE bit, encode bit A0 to 0.
Places device in a mode to pass SDI data to SDO with
one clock delay. Used for programming and testing
devices through serial connected controls.
