Most likely both - I2C or SPI wont really be very sensible for ion sense
data, but it'll be sueful for making simple (say, pic based) ECUs /
debugging on a laptop.

For high speed access it'll be memory mapped. its got a 16 bit address
space (not all used) and data bus width would be as wide as possible
given CPLD/FPGA/board/ARM pinout / routing requirements.
