SMOD
Serial Port 0 Baud Rate Doubler Enable. The serial baud rate doubling function for Serial Port 0.
bit 7
0: Serial Port 0 baud rate will be a standard baud rate.
1: Serial Port 0 baud rate will be double that defined by baud rate generation equation.
GF1
General-Purpose User Flag 1. This is a general-purpose flag for software control.
bit 3
GF0
General-Purpose User Flag 0. This is a general-purpose flag for software control.
bit 2
STOP
Stop Mode Select. Setting this bit halts the internal oscillator and blocks external clocks. This bit always reads as 0.
bit 1
Exit with RESET. In this mode, internal peripherals are frozen and I/O pins are held in their current state. The ADC is
frozen, but IDAC and VREF remain active.
IDLE
Idle Mode Select. Setting this bit freezes the CPU, Timer 0 and 1, and the USART; other peripherals remain active.
bit 0
This bit will always be read as a 0. Exit with AIE (A6h) and EWU (C6h) interrupts (refer to Figure 6 for clocks affected
during Idle mode).

Timer 1 Overflow Flag. This bit indicates when Timer 1 overflows its maximum count as defined by the current mode.
bit 7
This bit can be cleared by software and is automatically cleared when the CPU vectors to the Timer 1 interrupt service routine.
0: No Timer 1 overflow has been detected.
1: Timer 1 has overflowed its maximum count.
TR1
Timer 1 Run Control. This bit enables/disables the operation of Timer 1. Halting this timer preserves the current
bit 6
count in TH1, TL1.
0: Timer is halted.
1: Timer is enabled.
TF0
Timer 0 Overflow Flag. This bit indicates when Timer 0 overflows its maximum count as defined by the current mode.
bit 5
This bit can be cleared by software and is automatically cleared when the CPU vectors to the Timer 0 interrupt service routine.
0: No Timer 0 overflow has been detected.
1: Timer 0 has overflowed its maximum count.
TR0
Timer 0 Run Control. This bit enables/disables the operation of Timer 0. Halting this timer preserves the current
bit 4
count in TH0, TL0.
0: Timer is halted.
1: Timer is enabled.
IE1
Interrupt 1 Edge Detect. This bit is set when an edge/level of the type defined by IT1 is detected. If IT1 = 1, this bit
bit 3
will remain set until cleared in software or the start of the External Interrupt 1 service routine. If IT1 = 0, this bit will inversely
reflect the state of the INT1 pin.
IT1
Interrupt 1 Type Select. This bit selects whether the INT1 pin will detect edge- or level-triggered interrupts.
bit 2
0: INT1 is level-triggered.
1: INT1 is edge-triggered.
IE0
Interrupt 0 Edge Detect. This bit is set when an edge/level of the type defined by IT0 is detected. If IT0 = 1, this bit
bit 1
will remain set until cleared in software or the start of the External Interrupt 0 service routine. If IT0 = 0, this bit will inversely
reflect the state of the INT0 pin.
IT0
Interrupt 0 Type Select. This bit selects whether the INT0 pin will detect edge- or level-triggered interrupts.
bit 0
0: INT0 is level-triggered.
1: INT0 is edge-triggered.
