[Urgent Help] I'm lost... What "memory address" am I accessing on the XPT2046 to read coordinates? (My professor's question stumped me)

Have your instructor take a look a the the XPT2046 data sheet.

The device does not appear to have memory registers accessible to the data transfer protocol. It appears to be a state machine, implemented in a custom controller, possibly a programmable gate array. Or just an ASIC (special purpose IC).

Thank you so much for taking the time to explain this so thoroughly. Your help has been invaluable.
