MDBT42Q page documentation clarification needed

Sat 2019.03.30

While this content might better be addressed by @Gordon, others' comments welcome.

My questions resulted from an attempt connecting the Ublox NEO-6M to the MDBT42Q breakout. Surprisingly, communications and rendering data output in the WebIDE went without a hitch. Kudos to Gordon for concise documentation.

Beneath breakout board image:

Note: The nRF52 port has one available I2C, SPI and USART (and infinite software SPI and I2C)

Other questions resulted:

Q1: Is the 'nRF52 port' just a reference to pins D6 and D8 ? (what port?)
Q2: It is not possible to have both BLE and the NEO-6M communicating at the same time (?T one or the other?)
Q3: I presume that I2C and SPI are allowed only on pins D6 and D8 if Q1 is true (doc isn't really clear here, where are the hardware I2C and SPI?)
