07:26 PM Revision 06b45f17 (simtrace): schematic: mark P1 and P2 as dot no place

P1 (JTAG) and P2 (FTDI UART) are onlz needed to be placed on
boards meant for development.
this can by done by hand s... Kévin Redon

07:13 PM Revision bea9406b (simtrace): schematic: mark USB reset circuit as dot no place

the additional circuit to reset USB (by pulling D+ low) is not
required anymore since the USB controller in the SAM3S... Kévin Redon

06:33 PM Revision 614ce7a7 (simtrace): schematic: mark R19 as dot no place

R19 pulls VCC_PHONE low for better power on detection.
but the voltage divider R20 + R21 also pull this line low usin... Kévin Redon

03:52 PM Revision af693b2e (simtrace): schematic: rename NP to DNP for clarity

might get shorted when the board lies on a conductive s... Kévin Redon

03:40 PM Revision 2ad8ff81 (simtrace): schematic: mark R22 as dot no place

R22 is use to pull the FLAGB output of the FPF2109 high since this
is an open-drain output.
but we actually don't rea... Kévin Redon

03:20 PM Revision 3df5a7f2 (simtrace): schematic: mark R24 as no place

R24 is pulling the voltage regulator output for VCC_SIM down.
it has probably been added at the same time as R15.
sin... Kévin Redon

03:08 PM Revision 9cb8f504 (simtrace): schematic: mark R15 as no place

R15 is pulling VCC_SIM down.
it has probably been added because a load resistor is present in
the FPF2109 datasheet e... Kévin Redon
