I have used the AT89C51 programming to add extra functionality. Basically it allow you to add a keypad by ‘define’ the pins on the chip. I am not sure this is a legal way but so far so good. There are other IC to add for more complex keypad (piano keypad etc.). With some more programming this IC allow to define the pin position on the IC.

The default boot pins for the AT89C51 are:
\- CLK1,
\- RA6,
\- RB7,
\- RB4,
There is no clock output; instead, the external oscillator runs fast enough for operation. There is no voltage output (5-15V), thus, no special precautions need be taken in installation and

request for the kind attention of atmel AT89c2051 and its programmers. these programmers have been delivered by atmel. to some of our technicians, they fail to program the at89c2051 through its own system. it seems to be only a software problem. therefore, we request for your kind help in programming these chips without any program. i would appreciate if you could help me in this regard.

Rassie Erasmus, who was born in Pietermaritzburg and has played rugby in the city for most of his life, will have known all about serendipity since he was a boy.

On Thursday, he takes over from Steve Borthwick as coach of the Springboks. Erasmus coached the Bulls for nine seasons, and has been a confidant of Borthwick’s for a decade. He also has a reputation as a winner.

Erasmus is not a natural fit for the Boks, however. He is not a conservative coach, and he has shown his willingness to upset the applecart. In the Bulls’ fourth year in Super Rugby, they achieved the unthinkable by beating their previous premiership winners, the Western Force, in the semi-finals. The following year, his side beat the Lions in a knockout game at Ellis Park.

Last season, he coached the Boks for the entire series in the Commonwealth Games, including the gold medal. He has a reputation as a disciplinarian who expects his charges to be on their best behaviour; at Johannesburg-based Harlequins, he scolded a bunch of white-shirted players who, he felt, had over-indulged in a pre-match meal.

Erasmus has been eyed as a possible coach of the Eagles, but he has previously ruled himself out. He might have been tempted by coaching the Boks, but he has not shown any desire to leave the Bulls just yet.

The incumbent Boks coach, Allister Coetzee, is an ex-Rhodes player and has served the team for many years, so the Test line-up is in his hand. Coetzee has a reputation as a coach who knows his trade, but a rookie in charge of the Boks would have been a gamble – it has gone wrong before. A successful case can be made for what Mike Riddell was doing for the Lions in 1997 and for Brian Smith with
