SPI Connectivity
The phyCORE-OMAP44xx Carrier Board supports two SPI interfaces. The first one originates from the phyCORE-
OMAP44xx's SPI1 interface which is Master/Slave configurable and supports up to four peripherals (refer to
for details). This interface is available at the PHYTEC Extension Board (PEB) connectors X18 and
X19, as well as at the display data connector X12 and the expansion connector X5.
assignment of the SPI chip select signals to the different connectors.
The second SPI interface is derived from the Multichannel Audio Serial (McASP) interface pins of the phyCORE-
OMAP44xx as these pins embody the signals of the second SPI module SPI2 as alternative function. This inter-
face provides only one chip select signal (CS0). The second SPI interfaces is available at Expansion Connector
X5 (please refer to
for details on the correlation between McASP and SPI2 signals).
The signals of both SPI interfaces are translated from 1.8 V to 3.3 V.
