5: Host/Module Interfaces
This chapter provides information about specific host interface pin
assignments, the host-module communication interface (USB
interface), LED outputs, USIM interface, and lists extended AT
commands that may be useful for hardware integration testing.
Host interface pin details
Detailed connector pin information is available in the product
specification documents for each module—refer to these documents
when integrating modules into your host devices.
The following are specific integration considerations relating to the
host interface connector pins:
• On any given interface (USB, USIM, etc.), leave unused inputs
and outputs as no-connects.
• Tabl e 5- 1 and Tabl e 5- 2 on page 56 describe MC8775V and
MC8790V/MC8791V/MC8792V/MC8795V-specific pins that are
rated for 2.6 V. Reference these pins to the MSM_2.6 V rail (pin
11) as the maximum limit.
