Short Description
Opcode Fetch. Emulation
control line. A high level
driven by the controller dur-
ing output phase indicates
the beginning of a new
instruction.
This pin must be pulled low
to enable extended mem-
ory interface.
CVBS input for the acquisi-
tion circuit
Supply voltage for analog
components.
Ground for analog compo-
nents
Port 2 is a 4-bit port without
pull-up resistors.
----------
Port 2 has an alternate
function.
See Section on page 155.
Not connected
In slave mode horizontal
sync input or sandcastle
input for display synchroni-
zation.
----------
In master mode HS or VCS
output
Vertical sync input/ouput for
display synchronization.
----------
It also can be used as digital
input P4.7.
See Section on page 155.
----------
Furthermore, this pin can be
selected as an ODD/EVEN
indicator alternatively to
P3.0.
