Preliminary data
P89C51RA2/RB2/RC2/RD2xx
80C51 8-bit Flash microcontroller family

were successfully programmed. For a data record, an “X” indicates
that the checksum failed to match, and an “R” character indicates
that one of the bytes did not properly program. It is necessary to
send a type 02 record (specify oscillator frequency) to the
P89C51RA2/RB2/RC2/RD2xx before programming data.
The ISP facility was designed to that specific crystal frequencies
were not required in order to generate baud rates or time the
programming pulses. The user thus needs to provide the
P89C51RA2/RB2/RC2/RD2xx with information required to generate
the proper timing. Record type 02 is provided for this purpose.
