SPI registers map table
SPI frame has 7 bits address field and 20 bit data field, then the available address space consists of maximum
128 different registers. Taking into account the logical and physical partition of the functions configurable/
monitored by SPI interface, address space has been splitted in pages, each of 16 addresses.
Table below shows the SPI page vs. macro function distribution.
