Bit Description:

TCON.7:

TF1

ªTimer 1 Overflow Flagº:

Status bit set to 1 when Timer 1 overflows from a previous count value of all

1's. Cleared to 0 when CPU vectors to Timer 1 interrupt service routine.

Initialization:

Cleared to 0 on any type of reset.

TCON.6:

TR1

ªTimer 1 Run Controlº:

When set to a 1 by software, Timer 1 operation will be enabled.

Timer 1 is disabled when cleared to 0.

Initialization:

Cleared to 0 on any type of reset.

TCON.5:

TF0

ªTimer 0 Overflowº:

Status bit set to 1 when Timer 0 overflows from a previous count value of all

1's. Cleared to 0 when CPU vectors to Timer 0 interrupt service routine.

Initialization:

Cleared to 0 on any type of reset.

TCON.4:

TR0

ªTimer 0 Run Controlº:

When set to a 1 by software, Timer 0 operation is enabled. Timer 0 is dis-

abled when cleared to 0.

Initialization:

Cleared to 0 on any type of reset.

TCON.3:

IE1

ªInterrupt 1 Edge Detectº:

Set to 1 to signal when a 1±to±0 transition (IT=1) or a low level (IT=0) has

been detected on the

pin. Cleared to a 0 by hardware when interrupt

INT1

processed only if IT1=1.

Initialization:

Cleared to 0 on any type of reset.

TCON.2:

IT1

ªInterrupt 1 Type Selectº:

When set to 1, 1±to±0 transitions on INT1will be used to generate interrupt

requests from this pin. When cleared to 0,

is level-activated.

INT1

Initialization:

Cleared to a 0 on any type of reset.

TCON.1:

IE0

ªInterrupt 0 Edge Detectº:

Set to a 1 to signal when a 1±to±0 transition (IT0=1) or a low level (IT0=0)

has been detected on the

pin. Cleared to a 0 by hardware when inter-

INT0

rupt processed only if IT0=1.

Initialization:

Cleared to a 0 on any type of reset.
