UTILITY CONFIGURATION REGISTER
DESCRIPTION
1 = The 768 byte SRAM is located at 0x0400-
0x06FF in the Code Space, instead of
external Memory.
0 = The 768 byte SRAM is located at 0x0400-
0x06FF in the XDATA space.
Reserved. This bit should never be written to
a “1”.
1 = GPIO0 Output Auto Toggle enabled.
0 = Disabled, normal operation occurs.
GPIO4/SOF Output Select Mux
0 = GPIO4
1 = The IDE_nIOW signal is output.
P3.5 Timer 1 input trigger source
0 = GPIO3
1 = TBD
P3.4 Timer 0 input trigger source
0 = GPIO2
1 = TBD
GPIO1/TXD Output Select Mux
0 = GPIO1
1 = P3.1
P3.0 RXD/GPIO0 Input Select Mux
0 = RXD<=GPIO0
1 = RXD<='0'

Note 1:
GPIO0, when used as an output, will automatically toggle with 1second period and 50% duty cycle if
GPIO0_TOG is high.
