SFR Definition 21.1. TCON: Timer Control

Bit 7:

TF1: Timer 1 Overflow Flag.

Set by hardware when Timer 1 overflows. This flag can be cleared by software but is auto-

matically cleared when the CPU vectors to the Timer 1 interrupt service routine.

0: No Timer 1 overflow detected.

1: Timer 1 has overflowed.

Bit 6:

TR1: Timer 1 Run Control.

0: Timer 1 disabled.

1: Timer 1 enabled.

Bit 5:

TF0: Timer 0 Overflow Flag.

Set by hardware when Timer 0 overflows. This flag can be cleared by software but is auto-

matically cleared when the CPU vectors to the Timer 0 interrupt service routine.

0: No Timer 0 overflow detected.

1: Timer 0 has overflowed.

Bit 4:

TR0: Timer 0 Run Control.

0: Timer 0 disabled.

1: Timer 0 enabled.

Bit 3:

IE1: External Interrupt 1.

This flag is set by hardware when an edge/level of type defined by IT1 is detected. It can be

cleared by software but is automatically cleared when the CPU vectors to the External

Interrupt 1 service routine if IT1 = 1. When IT1 = 0, this flag is set to ‘1’ when /INT1 is active

as defined by bit IN1PL in register IT01CF (see SFR Definition 10.7).

Bit 2:

IT1: Interrupt 1 Type Select.

This bit selects whether the configured /INT1 interrupt will be edge or level sensitive. /INT1

is configured active low or high by the IN1PL bit in the IT01CF register (see SFR Definition

10.7).

0: /INT1 is level triggered.

1: /INT1 is edge triggered.

Bit 1:

IE0: External Interrupt 0.

This flag is set by hardware when an edge/level of type defined by IT0 is detected. It can be

cleared by software but is automatically cleared when the CPU vectors to the External

Interrupt 0 service routine if IT0 = 1. When IT0 = 0, this flag is set to ‘1’ when /INT0 is active

as defined by bit IN0PL in register IT01CF (see SFR Definition 10.7).

Bit 0:

IT0: Interrupt 0 Type Select.

This bit selects whether the configured /INT0 interrupt will be edge or level sensitive. /INT0

is configured active low or high by the IN0PL bit in register IT01CF (see SFR Definition

10.7).

0: /INT0 is level triggered.

1: /INT0 is edge triggered.
