RPi Guzunty connection summary

I found the jumper things are blocking my eyes seeing the schematic, so I cut and pasted a map without the messy jumpers.

Now I can see the RPi Guzunty Pi connection.  I am making a summary.

1. JTAG - 4 pins

2. SPI - 5 pins

3. I2C - 2 pins

4. GCK 1, 2 - 2 pins

5. PWM - 1 pin (also = GCK2?)

6. GPIO_GEN6 - 1 pin

7. TxD, RxD - 2 pins

Total = 17 pins.

I also found the FB1,2,3,4 very tediously confusing.  I gave up after trying to sort out which group belongs to which group.  I think as a newbit, I should just start from the small tree GCLK, and forget the big forest.
