Places the device in scan mode.
Places the device in scan mode.
Reset, along with an Update operation (UPDATE# pin
or Update command) resets the entire Crosspoint Array
to no-connect (B7 and B8 are not changed).
Use the Address Register as the Input address to be the
broadcast input. Connects the selected Input to all
Output cells and disconnects all other Inputs.
Activating the Global Update instruction returns the
Crosspoint array from the Broadcast mode to the
previous programed state.
Programs the Output Buffer address specified in the
Serial instruction (A6-A0). The configuration data is
also specified in the Serial instruction bits BA-B7. See
Table 8 for bit assignment of the Buffer functionality.
Readback the connectivity of the Crosspoint cell with
the Input location specified in the Address Register
and the Output location specified Serial instruction
(A0-A6). It also returns the configuration of the Output
Buffer addressed in the Serial instruction (A0-A6).
The readback data is shifted out of SDO in the
following sequence:
NOTE: This instruction does not increment the
Address Register. This instruction also requires two
DR cycles
Update the programmed connection from the Loading
SRAM to the Active SRAM.
Disconnect the Crosspoint connections from the Input
address specified in the Address Register.
Disconnect the Crosspoint cell at the Input location
specified at the Address Register and the Output
location specified in the Disconnect instruction (A6-
A0).
All other connections from the same input address or
to the same output address remain the same.
1. Crosspoint Connect (1=connected, 0=no
2. Output Enable—B7 (see Table 8)
3. Output Enable—B8 (see Table 8)
4. Reserved (Don’t Care)
5. Reserved (Don’t Care)
6. State of Broadcast bit
7. State of the RCE bit
