Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
When 1, an interrupt occurs when a phase error is detected.
When 1, an interrupt occurs when the direction changes.
When 1, an interrupt occurs when the velocity timer expires.
When 1, an interrupt occurs when the index pulse is detected.
