FUNCTIONAL DESCRIPTION
CORE: Core Module interconnects all the sub-modules in the SPI IP. Ports of core module are the top level ports for the SPI IP.
FSM: FSM Module generates the SPI transcations on SPI Master based on commands from CSR block. This blocks implements all the features of SPI specifications.
ARB: Arbiter Module selects the read write operation of DMA and FSM module to access the CSR module.
DMA: DMA Module is used to write/read the data to/from DMA memory through SoC master interface.
CSR: CSR Module has all the registers. The contents of the registers are decoded and assigned to its respective output ports based on its functionality.
