7174 - MachXO3D: Why MachXO3D has two ranges for I2C glitch filter?
MachXO3D glitch filter has to option (8 to 25 ns) and ( 16 to 50 ns). The filter only works in these two ranges as the filter is digitally implemented the filter may work properly in these two ranges. The filter modes are tested on typical value 10ns and 20 ns for 8 to 25 ns and 16 to 50 ns settings respectively.
If customer wants to use an accurate filter we do not recommend them to use the internal filter.

The MachXO JTAG pins on the MACHXO Mini board share the same traces with some generic IOs of the MachXO device (as shown on page 4 and page 2 of the schematic). If the new design patterns have signals driving out of these pins, they could potentially ...

A fundamental rule for TransFR, there should be no IO design change (add, remove, alter the IO standard or alter IO direction) between the two bitstreams before and after the TransFR, because the purpose of TransFR is to hold the IO standard and ...

The way to check the MachXO configuration status through JTAG is to use the capture instruction. For the MachXO the capture instruction (which is the instruction shifting out of the instruction register) is 0x19 (if the device is blank) or 0x1D (if ...
