Regarding the in-system programming procedure, ATMEL currently recommends the
following ISP waveforms for implementing the ISP programming algorithm in the
AT89S-series devices:
These waveforms should be used in addition to the serial downloading waveforms
shown in the respective device datasheets.

RST
(>2 machine cycles)
A (<1/2 machine cycle)
(>1 machine cycle)
SCK 7 6
GND
VCC
This glitch MAY occur in certain systems because when RST
goes high, port 1 pins will be driven with a strong pullup for
one clock cycle; if the glitch does occur, it can be interpreted
incorrectly as the first SCK pulse of a serial data stream.
So the falling edge of RST at point A is necessary to
clean-up the internal state machine.
should be powered
