I/O CONTROL
The CT2500 is very flexible in it’s I/O architecture.
The unit can handle 16 bit and 32 bit data and
command word loading. In addition, data words can
be preloaded into an external FIFO and the unit will
load data words from the FIFO directly without
subsystem intervention. Similarly, data can be
received and automatically loaded into a FIFO. This
frees up the subsystem until the data transfer is
complete. These options are desirable especially
when operating under burst mode transmissions.
Control frames are sent by strobing LDCNTRL and
data is sent by strobing STR2.
DATA TRANSFERS
The CT2500 is built to send and receive Type D
and E Control frames. It can transmit and receive
32-bit command and data word. All 32-bit
communications are double buffered for maximum
flexibility. This allows the subsystem to respond with
less critical timing constraints. Burst mode data
transmission can be initiated by setting the "Burst
Mode" pin high. Automatic FIFO operation is
enabled by setting "FIFOEN" pin high. The serial
data out is automatically formatted for the CT1698 to
send out along the cable.
SOURCE AND SINK MODES
Both Source and Sink Mode operations are
available in the CT2500. Selection of modes is
accomplished through the Source/Sink pin. In the
Source Mode, the unit will transmit control frames,
32 bit command and data words including burst
mode data. It will receive control frames only. In Sink
Mode, the unit will transmit control frames only and
receive control frames, 32 bit command and data
words, and burst mode data.
SYSTEM INTEGRITY FEATURES
The CT2500 has built in system integrity features.
The unit can generate and send parity with all 32 bit
transmissions. For reception of 32 bit words, the unit
can check for parity, frame, overrun, sync, and bit
count errors.
