18.2 Operation

Accesses to addresses H'FFFE000âH'FFFFFFF (SH7032) or addresses H'FFFF000âH'FFFFFFF

(SH7034) are directed to the on-chip RAM. Memory area 7 (H'F000000âH'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

Controller (BSC).
