Auxiliary SPI Port [J7]

The Auxiliary SPI port, labeled
optional external SPI Encrypting IntelliHead with MagneSafe V5. It is a 10-pin 1.25mm pitch Molex
PicoBlade header designed to mate with Molex PicoBlade connector 51021-1000. The dot on the printed
circuit board indicates pin 1. Pinouts are shown in Figure 2-4.
Depending on usage, the auxiliary SPI port can provide up to 100mA @ 3.3V to power an external SPI
device.
For details about connecting to an SPI Encrypting IntelliHead with MagneSafe V5, see the Installation
and Operation Manual or Technical Reference Manual for the module you plan to connect. Wiring
specifications for SPI heads are shown in Table 2-1. Programmers should see section 5 Developing
Custom Software for cross-references to programming tools and documentation for communicating
through the port.
