6.4
This is the interface to the non-volatile memory
that contains the firmware. See
be either ROM, NVRAM – FLASH, or EEPROM,
or any combination of these types of memory. This
interface can also connect to SRAM that would em-
ulate a ROM on a development system. The bus
width is 8 or 16 bits. Except for the NVM_WE_N
and NVM_OE_N pins, all these pins are shared
with the DRAM interface, which operates simulta-
neously with the ROM/NVRAM interface.

Memory Data Bus. Use M_D[7:0] for 8-bit interface
Memory Address Bus[11..0]
Memory Address Bus[23..12]
16-bit data mode, M_D[26:16] is upper word address.
For 8-bit data mode, M_D[27:16] is upper byte address.
Address decode low. Copy of address MSB.
Address decode high. Compliment of address MSB.
NVRAM Write Enable.
ROM/NVRAM Output Enable.
27 Mhz Clock Output.
Horizontal Sync. Output when the CS98000 is the video
master, input when the video encoder is master.
Vertical Sync. Output when the CS98000 is the video mas-
ter, input when the video encoder is master.
Video Data Output[7..0] in Cb,Y,Cr,Y format.
6.5
This is the interface to a video encoder chip that
will send the CS98000 video signals to a TV. See
Figure
CCIR-656. The CS98000 supports both master and
slave configuration. For CCIR-656 mode, the
CS98000 must be the sync master. In this case, the
HSYNC and VSYNC pins can be redefined as
GPIOs
20. The output format is either CCIR-601 or
