Bit 7
Serial Port 0 Baud Rate Doubler Enable. This bit enables/disables the
serial baud rate doubling function for Serial Port 0.
0 = Serial Port 0 baud rate will be that defined by baud rate generation
equation.

1 = Serial Port 0 baud rate will be double that defined by baud rate generation
equation.
Framing Error Detection Enable. This bit selects function of the
SCON0.7 and SCON1.7 bits.
0 = SCON0.7 and SCON1.7 control the SM0 function defined for the
SCON0 and SCON1 registers.
1 = SCON0.7 and SCON1.7 are converted to the Framing Error (FE) flag for the
respective Serial Port.
Reserved. Read data is indeterminate.
General Purpose User Flag 1. This is a general purpose flag for software
control.
General Purpose User Flag 0. This is a general purpose flag for software
control.
Stop Mode Select. Setting this bit will stop program execution, halt the CPU
oscillator, and internal timers, and place the CPU in a low-power mode. This bit
will always be read as a 0. Setting this bit while the Idle bit is set will place the
device in an undefined state.
Idle Mode Select. Setting this bit will stop program execution but leave the
CPU oscillator, timers, serial ports, and interrupts active. This bit will always be
read as a 0.
