Hi,
I'm trying to determine how many SPI modules are available on Concerto's F28M35H52C device as different sources seem to provide different information.
The TI website states that device has 5 SPI interfaces - 1 (one) on C28 core and 4 (four) on Cortex-M3 core. The same information is provided by the device's data sheet.
However the technical reference manual SPRUH22G states it in different ways depending on the specific section of the document. For instance, it states in Chapter 22, p.1604, that Concerto microcontroller includes 2 (two) synchronous serial interface (SSI) modules and each of them is capable of supporting SPI functionality. Same thing is stated in sub-chapter 22.5, Register Map, p.1616, that lists only 2 (two) SSI modules - namely SSI0 and SSI1. But to the contrary, Table 4-2, GPIO Pins and Alternate Mode Functions, pp.340-341, shows that modules SSI2 and SSI3 are also available.
So, in the reality, how many SPI interfaces are available on this device? And what are the base addresses for currently unlisted SSI2 and SSI3 modules if they're really available?
