SPI interface
The LS1021A / LS1020A serial peripheral interface (SPI) pins may be used for off-board SPI device
access: For various SPI memory devices or SPI controller of various TWR modules.
Figure 2-16 shows the overall connections of the two SPI portions.

-
miniPCIe2 Slot
Slave address depends on
miniPCIe cards on the slot.

-
TWR-ELEV Pin NO. A7, A8
Slave address depends on TWR
modules on the ELEV.
Note: “7b” addresses do not include the R/W bit as an address member, though some datasheets might do so. For
consistency, all I2C addresses are 7 bits of address only.
