Functional Description

READ WORD

To check the status of a CS212's inputs: i.e., IN0 and IN1 or

Control

Circuit

212

IN2-3, a read word must be sent. The first 5 bits must cor-

respond to the address of the CS212 to be interrogated. Bit

#6 is the address parity bit. It must insure that the first 6

bits are an even number of "1" 's. If the parity is even and

the CS212 to be interrogated has not previously received a

parity error (odd parity), it will transmit its status, along

with an internally generated parity bit. D0 corresponds to

IN0, D1 corresponds to IN1 or IN2-3. After the address

parity bit has been transmitted the controller must pull the

line down to about 7.5V to allow the CS212 to transmit. If a

"1" is to be transmitted, no change will occur on the line. If

a "0" is to be transmitted, the CS212 will then pull the line

down. In either case, the controller must pull the line back

up to 15V in order to continue. If the CS212 has received a

parity fault, it will transmit 3 one's (D0=D1=P_D=1). This

will allow the controller to detect a parity error. If a parity

error is detected by the controller, the read word must be

repeated.

Transmitted

by CS-212

Transmitted

by Controller

A typical line signal from the control unit would look like

the following:

Data Parity

IN 1 Status

IN 0 Status

"0" for Read

Add Parity

The CS212 would decode this into clock and data.

Clock

Positive Edge Strobes

A4=1 x 2⁴= 16

Data into an Internal

A3=1 x 2³= 8

Shift Resister

A2=0 x 2²= 0

Data

A1=0 x 2 = 0

A0=0 x 2⁰= 0

Binary = #24

The CS212 accepts addresses and commands in 10-bit word

formats. Three types of words must be generated: Sync,

Read and Write.

TYPICAL READ WORD

Assume that device #24 is to be interrogated and the status

of IN0=1 and IN1=0.

SYNC

READ₁READ₂READ₃READ₂₉SYNC WRITE₁WRITE₂

WRITE₂₉

SYNC WORD

WRITE WORD

Synchronization is obtained by providing the CS212 with 8

or more 1's followed by a "0". To prevent a false sync, it is

best to send 0 before the eight 1's. This word insures all cir-

cuits on the same line see the commands at the proper

time.

In order to update OUT0 and OUT1, a write word must be

sent to the CS212. The first 5 bits must correspond to the

CS212 to be updated. Bit #6 is an address parity bit. It must

insure even parity. D0 corresponds to OUT0 and D1 corre-

sponds to OUT1. An even data parity bit must be received

by the CS212. If the address and data parity are even and

the CS212 has not previously received a parity error, it will

update OUT0 and OUT1. If a parity error was received, the

CS212 will not be updated. In this case, a read word must

be sent to clear the parity fault.
