5.20. Video DAC
SPHE8200 contains 6-channel 10-bit high-speed current-source
DACs operating from 27MHz to 60MHz (for 480p/576p or SVGA
display). The DAC outputs can drive a 37.5Ohm load directly.
5.21. ATAPI interface
SPHE8200 also supports ATAPI interface directly without glue
logic. Although the SPHE8200 has integrated DVD/CD servo
logics, with this interface the application could support other
ATA/ATAPI compliant devices directly. The ATAPI/IDE interface is
a standard ATA-5 host interface capable of PIO mode 2 to PIO
mode 4 to external devices. By implementing this interface system
based DVDROM loaders or other ATA compliant devices.
5.22. GPIO
In SPHE8200 almost every pin that related to selectable features
can serve as general-purpose input-output control function. When
a pin is programmed to this mode, the RISC can take full control
over the direction and output level.
5.23. UART
Two
UART
channels
are
provided
for
debugging
or
communication purpose. The UART can support standard serial
port baud-rate and formats. It also supports auto baud-rate
detection and hardware flow-control (CTS/RTS pair).
