Accesses to addresses H'FFFE000–H'FFFFFFF (SH7032) or addresses H'FFFF000–H'FFFFFFF
(SH7034) are directed to the on-chip RAM. Memory area 7 (H'F000000–H'FFFFFFF) is divided
into shadows in 8 kbyte units for the SH7032 and 4-kbyte units for the SH7034. All shadow
accesses are on-chip RAM accesses. For more information on shadows, see section 8, Bus State
