Items Specification
Bus state controller
(BSC)
•
Physical address space divided into eight areas, four areas (area 0,
areas 2 to 4), each a maximum of 64 Mbytes and other four areas
(areas 5A, 5B, areas 6A, 6B), each a maximum of 32 Mbytes
•
The following features settable for each area independently
Bus size (8, 16, or 32 bits), but different support size by each areas
Number of wait cycles (wait read/write settable independently area
exists)
Idle wait cycles (same area/another area)
Specifying the memory to be connected to each area enables
direct connection to SRAM, SDRAM, Burst ROM, address/data
MPX mode supporting area exists
Outputs chip select signal (
CS0
,
CS2
to
CS4
,
CS5A/B
,
CS6A/B
)
for corresponding area (selectable for programming CS
assert/negate timing)
•
SDRAM refresh function
Supports auto-refresh and self-refresh mode
•
SDRAM burst access function
•
Area 2/3 enables connection to different SDRAM (size/latency)
Direct memory access
controller (DMAC)
•
Number of channels: four channels (two channels can accept external
requests)
•
Two types of bus modes
Cycle steal mode and burst mode
•
Interrupt can be requested to the CPU at completion of data transfer
•
Supports intermittent mode (16/64 cycles)
User debugging
interface (H-UDI)
•
E10A emulator support
•
JTAG-standard pin assignment
•
Realtime branch trace
