f
OSC
in 6-clock mode).
ALE is active only during off-chip memory access.
Internal/External RAM access using MOVX @Ri/@DPTR
EXTRAM
Operating Mode
0
Internal ERAM access using MOVX @Ri/@DPTR.
1
External data memory access.
Fast Mode Enable, switches between the Standard and the Fast data-transfer mode for the SIO1 I
2
C serial port (a
one-time set bit, cleared by chip-reset only)

Operating Mode
0
100 Kbit/s Standard mode selected.
1
400 kbit/s Fast mode selected.
Slew-Rate control-circuit Disable, switches between the minimum and the maximum slew-rate of the SCL1 and SDA1 pins
of the SIO2 I
2
C serial port.
SRD

NOTE:
*User software should not write 1s to reserved bits. These bits may be used in future 8051 family products to invoke new features. In that case, the reset or inactive value
of the new bit will be 0, and its active value will be 1. The value read from a reserved bit is indeterminate.
