*1: For the number of steps when extension devices are used or when index qualification is performed to
bit devices for AnA, A2AS, AnU, QCPU-A (A Mode) and A2USH board, refer to Section 3.8.1.
*2: The
mark in the Index column indicates that index qualification can be performed with the AnA,
A2AS, AnU, QCPU-A (A Mode) and A2USH board only.
*3: The
mark in the Subset column indicates that subset processing can be performed with the A3H,
A3M, AnA, A2AS, AnU, QCPU-A (A Mode) and A2USH board only.
