is read before the 8051 is out of reset. This rate cannot be modified once the 8051 is running. The 8051 may examine internal
register bits to determine the frequency at which it is operating.
The CLKOUT pin, which can be three-stated and inverted using internal control bits, outputs the 50% duty cycle 8051 clock, at
the selected 8051 clock frequency
—
48, 24, or 12 MHz.
3.2.2
FX2 contains two standard 8051 UARTS, addressed via Special Function Register (SFR) bits. The UART interface pins are
available on separate I/O pins, and are not multiplexed with port pins.
UART0 and UART1 can operate using an internal clock at 230 KBaud with no more than 1% baud rate error. 230-KBaud operation
is achieved by an internally derived clock source that generates overflow pulses at the appropriate time. The internal clock adjusts
for the 8051 clock rate (48, 24, 12 MHz) such that it always presents the correct frequency for 230-KBaud operation.
NOTE:
115-KBaud operation is also possible by programming the 8051 SMOD0 or SMOD1 bits to a
“
1
”
, for UART0 and/or UART1,
respectively.

3.2.3
Certain 8051 SFR addresses are populated to provide fast access to critical FX2 functions. These SFR additions are shown in
Table 3-1
. Bold type indicates non-standard, enhanced 8051 registers.
The two SFR rows that end with
“
0
”
and
“
8
”
contain bit-addressable registers. The four I/O ports A
–
D use the SFR addresses
used in the standard 8051 for ports 0
–
3, which are not implemented in FX2.
Because of the faster and more efficient SFR addressing, the FX2 I/O ports are not addressable in external RAM space (using
the MOVX instruction).
Special Function Registers (SFR)
3.3
FX2 supports the I
2
C compatible bus as a master only at 100/400 kbits/s. SCL and SDA pins have open-drain outputs and
hysteresis inputs. These signals must be pulled up to 3.3V, even if no I
2
C compatible device is connected.
