For the Lattice MachXO device, all the registers in the device will be reset upon power-up of the device, provided the power-up sequence is clean. This will happen without any additional effort on the part of the user. The software will evaluate the ...
Even if you do not use the GSR/LSR logic in RTL, GSR is always used during bitstream download. During bitstream download all flip flops are held at reset until the download is completed. So, the state of a register's Q output is always '0' or LOW at ...
Floating IO pin is not recommended. If IO pins are left floating, then the input transistors might fall outside of the saturation or cut-off region. As a result, the device could draw additional current and increase the device's power consumption. If ...
If you disable an LDO or DC-to-DC converter being trimmed bya POWR6AT6 or POWR1220, their trim circuitry will still attempt to perform the trim operation, except that it will now see '0' V as the feedback voltage. This will result in the TRIM output ...
