Notes: *1 When MD2–MD0 pins are 010 (SH7034)
*2 When MD2–MD0 pins are 000 or 001
*3 Select with MD0 pin
*4 Select with DRAME bit in BCR
*5 Divided into 8-bit and 16-bit space according to value of address bit A8. (Longword
accesses are inhibited, however, for on-chip supporting modules with bus widths of 8
bits. Some on-chip supporting modules with bus widths of 16 bits also have registers
that are only byte-accessible and registers for which byte access is inhibited. For
details, see the sections on the individual modules.)
*6 Divided into 8-bit space and 16-bit space by value of address bit A14
*7 Select with IOE bit in BCR
*8 For SH7032
*9 For SH7034
