FUNCTIONAL DESCRIPTION

8052 INSTRUCTION SET

Table 4 documents the number of clock cycles required for each

instruction. Most instructions are executed in one or two clock

cycles, resulting in a 16 MIPS peak performance when operating

at PLLCON = 00H on the ADuC842/ADuC843. On the ADuC841,

20 MIPS peak performance is possible with a 20 MHz external

crystal.
