IAGRAM

The L29C525 is a high-speed, low

power CMOS pipeline register. It is

pin-for-pin compatible with the AMD

Am29525. The L29C525 can be

configured as two independent 8-level

pipelines or as a single 16-level

pipeline. The configuration imple-

mented is determined by the instruc-

tion code (I

The I

internal routing of data and loading of

each register. For instruction I

(Push A and B), data applied at the

on the rising edge of CLK. The

contents of A0 simultaneously move

to register A1, A1 moves to A2, and so

on. The contents of register A7 are

wrapped back to register B0. The

registers on the B side are similarly

shifted, with the contents of register

B7 lost.

Instruction I

similarly to the Push A and B

instruction, except that only the B side

registers are shifted. The input data is

applied to register B0, and the

contents of register B7 are lost. The

contents of the A side registers are

unaffected. Instruction I

A) is identical to the Push B

instruction, except that the A side

registers are shifted and the B side

registers are unaffected.

Instruction I

internal data movement. It is equiva-

lent to preventing the application of a

clock edge to any internal register.

The contents of any of the registers is

selectable at the output through the

use of the S

independence of the I and S control

lines allows simultaneous reading and

writing. Encoding for the S

is given in Table 3.
