DRAM Start Address Setup. Program the 21-bit WORD address to BA + 18H (bits 7-0), BA
+ 19H (bits 15-8), then BA + 1AH (bits 20-16).
Read Access Mode Setup. Program 0 to bit 0 of BA + 1BH to select read mode.
W99681CF then starts accessing 16-bit DRAM data into the internal latches, and the
internal DRAM address will be increased by 1 automatically after the access.
Read Low-Byte DRAM Data. Read low-byte DRAM data from BA + 1CH location.
Read High-Byte DRAM Data. Read high-byte DRAM data from BA + 1DH location. The
W99681CF starts accessing the next-address DRAM data and the internal DRAM address
will be increased by 1 automatically after the access.
Read Contiguous DRAM Data. Repeat steps 3 and 4 for contiguous DRAM data
accesses.

7.8.5 IHV-Specific Information
The microcontroller can provide IHV-specific information including Vendor ID, Product ID, Device
release number, and string descriptors of manufacturer, product, and device
′
s serial number as that of
E
2
PROM to save the cost of an E
2
PROM. Maximum 128 bytes information can be provided and data
structure is the same as that of E
2
PROM shown in Table 7.14. All IHV-specific information must be
written to the W99681CF via the Vendor String Data Port register (CR0F) in word-aligned sequence
right after hardware reset and base address is set up.
