Inversion circuit for direct and indirect conventions for an electronic module

摘要

The circuit is between a microprocessor (PRC) and a communication module (MOD). The module sends the processor a signal indicating the data word convention. The circuit has an inversion circuit (HARD) which can optionally invert or not invert the order of bits in a word as a function of the data word convention signal during transfer of a data word between processor and module.
