ADuC841/ADuC842/ADuC843
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.
