*Note: R127 is applicable only in 2.5 V~3.3 V (U9) range for LCMXO3LF-9400C device.
Warning:
Only one option should be enabled for each MachXO3 device power rail.
The ASC device (U7) acquires power from the 3.3 V LDO only. A jumper (JP1) needs to be installed to provide the power
and this can also be used as test point to measure current drawn by the ASC.
