256 Kbytes
16 Kbytes
Address space: A maximum 1 Mbyte for each of two areas (CS0 and
CS1) (SH7137 only)
8-bit external bus (SH7137 only)
The following features settable for each area independently
 Number of access wait cycles
 Idle wait cycle insertion
 Supports SRAM
Outputs a chip select signal according to the target area
Data transfer activated by an on-chip peripheral module interrupt can
be done independently of the CPU transfer.
Transfer mode selectable for each interrupt source (transfer mode is
specified in memory)
Multiple data transfer enabled for one activation source
Various transfer modes
Normal mode, repeat mode, or block transfer mode can be selected.
Data transfer size can be specified as byte, word, or longword
The interrupt that activated the DTC can be issued to the CPU.
 A CPU interrupt can be requested after one data transfer
 A CPU interrupt can be requested after all specified data transfer
Five external interrupt pins (NMI and IRQ3 to IRQ0)
On-chip peripheral interrupts: Priority level set for each module
Vector addresses: A vector address for each interrupt source
