Section 13 PCI Controller (PCIC)
For PCI memory space 2 accesses, bits 28 to 18 of a SuperHyway address are controlled by the
PCI memory bank mask register 2 (PCIMBMR2).
• PCIMBMR2 [28:18] B'1 1111 1111 11: PCI address [28:18] = SH address [28:18]
• PCIMBMR2 [28:18] B'0 1111 1111 11: PCI address [28:18] = PCIMBR2 [28], SH address [27:18]
• PCIMBMR2 [28:18] B'0 0000 0000 01: PCI address [28:18] = PCIMBR2 [28:19], SH address [18]
• PCIMBMR2 [28:18] B'0 0000 0000 00: PCI address [28:18] = PCIMBR2[28:18]
The upper three bits ([31:29]) of a SuperHyway bus address are replaced with bits 31 to 29 in PCI
memory bank register 2 (PCIMBR2).
