Specification
• 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
completion.
 A CPU interrupt can be requested after all specified data transfer
completion.
• 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
