Notes :
The host interface transfers data signals at a fixed width of 32 bits.
There are 23 lines for address signals handled in double words (
=
32 bits) and 32 Mbytes of address
space.
The external bus can be used at an operating frequency of 100 MHz maximum.
The RDY signal at the low level sets the ready state in the SH4 or V832 mode; the signal at the low level
sets the wait state in the SH3 mode. Note that the RDY signal is a tristate output.
The host interface supports DMA transfer using an external DMA controller.
The host interface generates a host processor interrupt signal.
The RESET pin requires low level input of at least 300
μ
s after setting “S” (PLL reset signal) to high level.
Fix the TEST signal at high level.
In the V832 mode, connect the following pins as specified :
SCARLET Pin Name
A24
DTACK
DRACK
Vide Output Interface
Pin Name
DCLKO
DCLKI
Notes :
The video output interface contains an 8-bit D/A converter to output analog RGB signals. Also, the
eight-bit RGB digital output pins can connect an external digital video encoder.
Using an additional external circuit, the video output interface can generate composite video signals.
The video output interface can provide display synchronized with external video. The mode for
synchronization with the DCLKI signal can be selected as well as the mode for synchronization with a set
dot clock as for normal display.
