The data field is used for the longword data specification.
The following two kinds of operation can be used on the OC data array:
1. OC data array read
2. OC data array write
Longword data is read into the data field from the data specified by the longword specification
bits in the address field in the OC entry corresponding to the way and entry set in the address
field.
The longword data specified in the data field is written for the data specified by the longword
specification bits in the address field in the OC entry corresponding to the way and entry set in
the address field. This write does not set the U bit to 1 on the address array side.
