4.6.2
The IC data array is allocated to addresses H'F100 0000 to H'F1FF FFFF in the P4 area. A data
array access requires a 32-bit address field specification (when reading or writing) and a 32-bit
data field specification. The way and entry to be accessed are specified in the address field, and
the longword data to be written is specified in the data field.
In the address field, bits [31:24] have the value H'F1 indicating the IC data array, the way is
specified by bit [13], and the entry is specified by bits [12:5]. CCR.IIX has no effect on this entry
specification. Address field bits [4:2] are used for the longword data specification in the entry. As
only longword access is used, 0 should be specified for address field bits [1:0].
The data field is used for the longword data specification.
The following two kinds of operation can be used on the IC data array:
1. IC data array read
2. IC data array write
Legend:
L:
Address field
Longword data is read into the data field from the data specified by the longword specification
bits in the address field in the IC 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 IC entry corresponding to the way and entry set in
the address field.
