Description
Double UART Baud Rate.
0 = Normal, 1 = Double Baud Rate.
Serial Power-Down Interrupt Enable. If this
bit is set, a serial interrupt from either SPI
or I

C can terminate the power-down
mode.
INT0 Power-Down Interrupt Enable.
If this bit is set, either a level (IT0 = 0) or a
negative-going transition (IT0 = 1) on the
INT0 pin terminates power-down mode.
If set to 1, the ALE output is disabled.
General-Purpose Flag Bit.
General-Purpose Flag Bit.
Power-Down Mode Enable. If set to 1, the
part enters power-down mode.

ADuC845/ADuC847/ADuC848 Configuration Register
(CFG845/CFG847/CFG848)
The CFG845/CFG847/CFG848 SFR contains the bits necessary
to configure the internal XRAM and the extended SP. By default,
it configures the user into 8051 mode, that is, extended SP, and
the internal XRAM are disabled. When using in a program, use
the part name only, that is, CFG845, CFG847, or CFG848.

EXSP
Extended SP Enable.
If this bit is set to 1, the stack rolls over
from SPH/SP = 00FFH to 0100H.
If this bit is cleared to 0, SPH SFR is
disabled and the stack rolls over from
SP = FFH to SP = 00H.

XRAMEN
If this bit is set to 1, the internal XRAM is
mapped into the lower 2 kbytes of the
external address space.
If this bit is cleared to 0, the internal XRAM
is accessible and up to 16 MB of external
data memory become available. See
Figure 8.
