An electronic circuit used in the control and operation of a mass storage system (30) is provided that includes an SSD channel (10), and a control circuitry (11) having a microprocessor (28) and a read only memory (ROM) (29). During an initialization routine, microprocessor (28) and the ROM (29) of the control circuitry (11) provide operational parameters to the SSD channel (10) through a data/parameter path (13). The SSD channel (10) receives these operational parameters and stores them in a parameter memory (22) so that a read channel (18) may access the operational parameters during read operations. During read operations, the read channel (18) receives a stored data signal from a disk/head assembly (12) and a preamplifier (14). The read channel (18) processes the stored data signal and provides an output digital data signal. The digital data signal is provided to the control circuitry (11) through the data/parameter path (13). Thus, at different times, the operational parameters and the digital data signal are both exchanged through the data/parameter path (13).
