2115 - MachXO2/XO3: While programming the Lattice MachXO2 device using JTAG pins, is it recommended to provide connections to the DONE, INITN, and PROGRAMN pins of the device, or are TCK, TMS, TDI, and TDO sufficient?

2115 - MachXO2/XO3: While programming the Lattice MachXO2 device using JTAG pins, is it recommended to provide connections to the DONE, INITN, and PROGRAMN pins of the device, or are TCK, TMS, TDI, and TDO sufficient?

In Lattice MachXO2/XO3 devices, JTAG ports can access both Flash and SRAM Memory. Therefore, it is not necessary to use INIT, DONE and PROGRAMN pins. TCK, TMS, TDI and TDO pins are sufficient to program and configure the device.
