A protocol for exchanging data signals (2001, 2002, 2001', 2002') via a galvanic isolation link (ISO, 12) between a first unit (101), such as a low-voltage controller interface, and a second unit (102), such as a high-voltage driver interface of a high-voltage devioe such as an electric motor (EM) comprises exchanging data signals in subsequent time slots of fixed time duration during which first data signals are sent from the first unit (101) and received by the second unit (102) and second data signals are sent from the second unit (102) in response to first data signals received from the first unit (101).The first data signals comprise polling signals sent from the first unit (101) to the second unit (102) at each one of the subsequent time slots as well as on-demand requests sent from the first unit (101) to the second unit (102) in response to respective access requests received by the first unit (101), from a microcontroller (MC) for instance. The second data signals comprise status response signals sent from the second unit (102) in response to polling signals from the first unit (101) as well as read signals from the second unit (102) sent from the second unit (102) in response to on-demand requests from the first unit (101) .
