• IDX: InDeX
0 = no Index input change since the last read of TC_QISR.
1 = the IDX input has change since the last read of TC_QISR.
• DIRCHG: DIRection CHanGe
0 = no change on rotation direction since the last read of TC_QISR.
1 = the rotation direction changed since the last read of TC_QISR.
• QERR: Quadrature ERRor
0 = no quadrature error since the last read of TC_QISR.
1 = A quadrature error occurred since the last read of TC_QISR.
• DIR: Direction
Returns an image of the actual rotation direction.
