9.13 IC Data Sheets
This section shows the internal block diagrams and pin layouts
of ICs that are drawn as "black boxes" in the electrical diagrams
(with the exception of "memory" and "logic" ICs).
9.13.1 Diagram B3C, T8F24EF (IC7724)
Bus formats
8u@32MHz - 8 bits unsigned data at 32 MHz
m8s@32MHz- multiplexed UV 8 bits signed data at 32 MHz
nu - n bits unsigned data at 64 MHz (if 0u for Y
black on 32+256 = 288, white on 256+5
ns - n bits signed data at 64 MHz
mns - multiplexed UV n bits signed data at 64 MHz
rns - repeated UV n bits signed data at 64 MHz
