boot device
SPI0_CS1# P31 SPI0 Master Chip Select 1 O
CMOS 1.8V Standby
SPI0_CK P44 SPI0 Clock O
CMOS 1.8V Standby
SPI0_DIN P45 SPI0 Master input / Slave output I
CMOS 1.8V Standby also referred to as MISO
SPI0_DO P46 SPI0 Master output / Slave input O
CMOS 1.8V Standby also referred to as MOSI
SPI1_CS0# P54 SPI1 Master Chip Select 0 O
CMOS 1.8V Standby See ESPI
SPI1_CS1# P55 SPI1 Master Chip Select 1 O
CMOS 1.8V Standby See ESPI
SPI1_CK P56 SPI1 Clock O
CMOS 1.8V Standby See ESPI
SPI1_DIN P57 SPI1 Master input / Slave output I
CMOS 1.8V Standby See ESPI
SPI1_DO P58 SPI1 Master output / Slave input O
CMOS 1.8V Standby See ESPI
Note : SPI0 is free to use on the carrier but support only one device through CS0
SPI1 supports a CAN bus controller on the module through CS0, that leaves CS1 free for a device on the carrier
