Miscellaneous
NOP
No operation
1
1. One cycle is one clock.
2. Cycles of MOVX instructions are four cycles when they have 0 wait state. Cycles of MOVX instructions are 4 + n cycles when they have n wait states.
3. Cycles of LCALL instruction are three cycles when the LCALL instruction comes from interrupt.
OTHER SINGLE-CYCLE CORE FEATURES
Timer Operation
Timers on a standard 8052 increment by 1 with each machine
cycle. On the ADuC841/ADuC842/ADuC843, one machine
cycle is equal to one clock cycle; therefore the timers increment
at the same rate as the core clock.
ALE
The output on the ALE pin on a standard 8052 part is a clock at
1/6th of the core operating frequency. On the ADuC841/
ADuC842/ADuC843 the ALE pin operates as follows. For a
single machine cycle instruction,ALE is high for the first half of
the machine cycle and low for the second half. The ALE output
is at the core operating frequency. For a two or more machine
cycle instruction, ALE is high for the first half of the first
machine cycle and low for the rest of the machine cycles.
External Memory Access
There is no support for external program memory access on the
parts. When accessing external RAM, the EWAIT register may
need to be programmed to give extra machine cycles to MOVX
commands. This is to account for differing external RAM access
speeds.
EWAIT SFR
SFR Address
9FH
Power-On Default
00H
Bit Addressable
No
This special function register (SFR) is programmed with the
number of wait states for a MOVX instruction. This value can
range from 0H to 7H.
