Accessing MicroMod Connector pin13 and pin15

[Neal]

I am using a MicroMod (MM) Teensy in a project. The MM schematic is here:

View attachment MicroMod-Teensy_V1_3.pdf

Thanks to the KurtE spreadsheets, I understand which MM pins are equivalent to which Teensy 4.x pins. But the two pins labeled pin 13 (RTS1) and pin 15 (CTS1) on the MM connector aren't connected to the Teensy in the schematic.

So if I want to use these two pins for Input, what pin numbers do I use in statements like pinMode(xx, Input)?

Are you using the M.2 Teensy 4.1 on a custom PCB, or are you using it on a SparkFun carrier board, and if it's the latter, which board?

I am using the Sparkfun ATP Carrier board for prototyping. The ATP Carrier schematic is here:

View attachment MicroMod_ATP_Carrier_Board_Schematic.pdf

Pin 13 (RTS1) and pin 15 (CTS1) are available on the ATP Carrier board connectors J23/24. My question is what Teensy 4.1 core pins do pins 13 and 15 correspond to?

There is a posted NewPinTest .ino .zip posted somewhere.

Assuming that sketch is doing the right thing and that the 1's on the schematic are dropped on the silkscreen as primary:

Using that here the ATP labeled pins "CTS" and "RTS" do not show as connected to the Teensy MicroMod.

In that same grouping on the schematic the TX/'TX1' is p#1 and the MCLK in p#23 and PinList shows that.

Again as @defragster stated, they did not connect up those two pins to anything within the Teensy Micromod board as you can see in their schematic



I asked about that during the beta cycle but...
