DESCRIPTION:
The IDT7200/7201/7202 are dual-port memories that load
and empty data on a first-in/first-out basis. The devices use
Full and Empty flags to prevent data overflow and underflow
and expansion logic to allow for unlimited expansion capability
in both word size and depth.
The reads and writes are internally sequential through the
use of ring pointers, with no address information required to
load and unload data. Data is toggled in and out of the devices
through the use of the Write (
W
) and Read (
R
) pins.
The devices utilizes a 9-bit wide data array to allow for
control and parity bits at the user’s option. This feature is
especially useful in data communications applications where
it is necessary to use a parity bit for transmission/reception
error checking. It also features a Retransmit (
RT
) capability
that allows for reset of the read pointer to its initial position
when
RT
is pulsed low to allow for retransmission from the
beginning of data. A Half-Full Flag is available in the single
device mode and width expansion modes.
The IDT7200/7201/7202 are fabricated using IDT’s high-
speed CMOS technology. They are designed for those
applications requiring asynchronous and simultaneous read/
writes in multiprocessing and rate buffer applications. Military
grade product is manufactured in compliance with the latest
revision of MIL-STD-883, Class B.

ADC0 and ADC1 sample signals separately, how to write interrupts? [LM3S]
Should the base addresses of ADC be ADC0_BASE andADC1_BASE respectively, or should they be unified asADC_BASE? Also, should interrupts be written for both modules or just one? I'm a little dizzy after...
