Dual Data Pointer
Description
in standard mode or 6 oscillator clock periods in X2 mode. For further information on X2 mode,
refer to the Section “X2 Feature”, page 14.
Slow peripherals can be accessed by stretching the read and write cycles. This is done using the
M0 bit in AUXR register. Setting this bit changes the width of the RD and WR signals from 3 to
15 CPU clock periods.
For simplicity,
do not provide precise timing information. For bus cycle timing parameters refer to the Section
“AC Characteristics”.

Notes:
Figure 7-5.
Notes:
The AT8xC51SND2C implement a second data pointer for speeding up code execution and
reducing code size in case of intensive usage of external memory accesses.
