Beaglebone schematic wrong??

The A3 bone schematic, dated 10-21-11 shows the following:

PR1PRU0_PRUR31_16/GPIO0_20
PR1_PRU0_PRU_R31_16/GPIO0_15

PR1PRU1R31_16/EMU2/GPIO0_19
PR1_PRU1_PRU_R31_16/GPIO0_14

Now, unless I'm reading this wrong it's showing GPIO0-20 as being on
the same PRU0 register 31 bit (16) as GPIO0-15??

Also, GPIO0-19 is on the same PRU1 register 31 bit (16) as GPIO0-14??

Are these doubled up??

I need to double check, but the signals do appear in more than one place on some of those PRU signals. Have you checked it against the datasheet?

According to the pinmux utility PRU0 R31 bit16 can be connected either ball D15 (mode 6) or ball D14 (mode 7). So the schematics may show this signal twice.
