part (via a rising edge of SCLK), provided the SENI input of that device is LOW. If multiple devices are
cascaded, the SENI input should be connected to the SENO output of the previous device. So when serial
loading of a given device is complete, its SENO output goes LOW, allowing the next device in the chain
to be programmed (SENO will follow SENI of a given device once that device is programmed). The SENI
input of the master device (or single device), should be controlled by the user.
has been completed. SENO follows SENI once programming of a device is complete. Therefore, SENO
will go LOW after programming provided SENI is LOW, once SENI is taken HIGH again, SENO will also
go HIGH. When the SENO output goes LOW, the device is ready to begin normal read/write operations.
If multiple devices are cascaded and serial programming of the devices will be used, the SENO output
should be connected to the SENI input of the next device in the chain. When serial programming of the
first device is complete, SENO will go LOW, thereby taking the SENI input of the next device LOW and
so on throughout the chain. When a given device in the chain is fully programmed the SENO output
essentially follows the SENI input. The user should monitor the SENO output of the final device in the chain.
When this output goes LOW, serial loading of all devices has been completed.
Data present on SI will be loaded on a rising edge of SCLK provided that SENI is LOW. In expansion
mode the serial data input is loaded into the first device in a chain. When that device is loaded and its SENO
has gone LOW, the data present on SI will be directly output to the SO output. The SO pin of the first device
connects to the SI pin of the second and so on. The multi-queue device setup registers are shift registers.
chain to complete programming of all devices. The SI of a device connects to SO of the previous device
in the chain. The SO of the final device in a chain should not be connected.
operations of the device are synchronous to TCK. Data from TMS and TDI are sampled on the rising edge
of TCK and outputs change on the falling edge of TCK. If the JTAG function is not used this signal needs
to be tied to GND.

reset upon power-up, thus it must be reset by either this signal or by setting TMS= HIGH for five TCK cycles.
If the TAP controller is not properly reset then the outputs will always be in high-impedance. If the JTAG
function is used but the user does not want to use TRST, then TRST can be tied with MRS to ensure
proper queue operation. If the JTAG function is not used then this signal needs to be tied to GND. An

that WADEN is HIGH. WADEN should be asserted (HIGH) only during a queue change cycle(s). WADEN
should not be permanently tied HIGH. WADEN cannot be HIGH for the same WCLK cycle as FSTR. Note,
