Hint: It's almost invariably easier to type the key words into
Gargoyle than to whi..., er, expostulate about what you don't know
enough about. It also has the bonuses that you get to know things
quicker and more completely and in your own way rather than just being
given the bits that the client thinks are relevant, and best of all,
perhaps, that way people may end up thinking you know a lot more than
you really do.

For your edification: TB045 is, not too surprisingly, a Microchip
document relating to the subject at hand.

"145027" is indeed jargon / shorthand, and is liable to be recognised
by those 'skilled in the art'.
The MC145026 and MC145027 are intended to mutually implement a few
channels of digital data transmission.
They use trinary addressing to reduce the number of address pins
needed - odds are that that snippet will cue your memory.

It seems likely that the OP really wants replies mainly from people
who have some grasp of the quadrant of the subject that he's working
in, rather than providing training along the way to people so that
they can attempt to answer him. But, maybe not.

Title:	 KEELOQ=AE Manchester Encoding Receive Routines
Name:	 TB045
Date:	 5/11/01
Author:	 Lucio Di Jasio
Description:	All KEELOQ=AE Encoders use a common code word format. They
all pack the bits of information in the same number and position in
the transmission sequence. While all the encoders offer a basic Pulse
Width Modulation (PWM) method to produce a signal that is suitable for
radio transmission, many Advanced KEELOQ Encoders (HCS360 and higher)
offer alternative methods. One such alternative method is Manchester
encoding. This Technical Brief shows PICmicro=AE microcontrollers
assembly routines to receive Manchester encoded transmissions. other
encoding systems, such as PWM.
