2.3.12 MPCIE1, MPCIE2 : Mini PCIe, mSATA
Both mSATA and mini PCIe share the same form factor and similar electrical
pinout assignments on their connectors. There was no clear mechanism to
distinguish if an mSATA drive or a Mini PCIe device is plugged into the socket until
recently that SATA I/O issued an ECN change (ECN #045) to redefine pin-43 on
mSATA connector as "no connect" instead of "return current path" (or GND).
When an mSATA drive is inserted, its pin-43 is "no connect", and the respective
pin on the socket is being pulled-up to logic 1. When a mini PCIe device is
inserted, its pin-43 forces the respective pin on the socket to ground, or logic 0.
The pin assignments of MPCIE1, MPCIE2 are listed in the following table :
