The motor driver (14) of an horological motor (M) consumes an important part of the electrical energy of the electronic circuit due to the fact that configuration data has to be transferred to configuration registers (18 1 , 18 2 , ..., 18 N ) before each turn/step. In order to reduce the power consumption a circuitry (18, 21, 11, 15, 13) is proposed, which detects a change in at least one of the configuration registers (18 1 , 18 2 , ..., 18N). This detection is used to trigger a refresh of the configuration registers only when actually a change in at least one of these configuration registers occurs. |
