22. PCI Controller (PCIC)
22.4.5
The access size is fixed at longword when accessing the PCIC local register using I/O read or I/O
write commands. Addresses are specified using 4-byte boundaries, and BE[3:0] is specified as
B'0000.
The data alignment in target transfers (I/O read and I/O write) is shown in figure 22.22.
22.4.6
The data alignment when accessing the PCIC configuration register using the target configuration
read and configuration write commands is shown in figure 22.23.
In the SH7751 the access size is fixed at longword. The BE[3:0] value is ignored. In the SH7751R
all BE combinations are valid.
