Autobaud Performances
The ISP feature allows a wide range of baud rates in the user application. It is also
adaptable to a wide range of oscillator frequencies. This is accomplished by measuring
the bit-time of a single bit in a received character. This information is then used to pro-
gram the baud rate in terms of timer counts based on the oscillator frequency. The ISP
f eature requi res that an i n i ti a l c harac te r (an upperc a s e U) be sent t o t h e
AT89C51RD2/ED2 to establish the baud rate. Table show the autobaud capability.
Command Data Stream
Protocol
All commands are sent using the same flow. Each frame sent by the host is echoed by
the bootloader.
