// Select the number of connected half-bridges to be used
// If only two half-bridges are used (one high, one low) than a motor with only 0.9A can be used,
// otherwise the controller will signal an over-current error.
// If you motor or application needs more, than multiple half-bridges can be connected.
// If you choose four half-bridges, than 1.8A can be reached.
// The following settings are possible:
// - 2U two half-bridges with 0.9A are used, which is sufficient for small motors. This is the default setting
// - 4U with 1.8A, which is sufficient for bigger motors like most computer fans
