Symbol
Function
SMOD1
Double Baud rate bit. If SMOD1 = 1, Timer 1 is used to generate the baud rate, and the
serial port is used in modes 1, 2, and 3.
SMOD0
FE/SM0 Selection bit.
0: SCON[7] = SM0
1: SCON[7] = FE,
BOF
Brown-out detection status bit, this bit will not be affected by any other reset. BOF
should be cleared by software. Power-on reset will also clear the BOF bit.
0: No brown-out.
1: Brown-out occurred
POF
Power-on reset status bit, this bit will not be affected by any other reset. POF should be
cleared by software.
0: No Power-on reset.
1: Power-on reset occurred
GF1
General-purpose flag bit.
GF0
General-purpose flag bit.
PD
Power-down bit, this bit is cleared by hardware after exiting from power-down mode.
0: Power-down mode is not activated.
1: Activates Power-down mode.
IDL
Idle mode bit, this bit is cleared by hardware after exiting from idle mode.
0: Idle mode is not activated.
1: Activates idle mode.
