FUNCTIONAL DESCRIPTION

CORE: Core module interconnects all the sub-modules in the MIPI APHY I2C SLAVE PAL IIP. Ports of core module are the top level ports for the MIPI APHY I2C SLAVE PAL IIP.

TU(Tunneling/Unifying): Tunneling and unifying acts as bridge within the I2C Adaptation layer for conversion between SEP (Service extension packets) and Non-SE. It will operates in any of three modes(Transparent,Legacy,Mixed modes) based on the Reception of SEP or Non -SEP packets.

CHUNK: when receiving a stream of chunks from the packing function, the chunking function uses the order sub-field to reassemble them into their original packets

PACK: It extracts the raw SEP application data from the incoming A-packet stream and sent to the I2C low level packet interface.

UNPACK: Packing function process the SYNC event messages/ Response packets and formatting into a standardized A-packets.

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.
