AT89LP213/214
The AT89LP213/214 is fully binary compatible with the MCS-51 instruction set. The difference
between the AT89LP213/214 and the standard 8051 is the number of cycles required to execute
an instruction. Instructions in the AT89LP213/214 may take 1, 2, 3 or 4 clock cycles to complete.
The execution times of most instructions may be computed using
Table 21-1.
