NOTE
1These bits are not used in the control of timer/counter 0 and 1, but are used instead in the control and monitoring of the external
INT0 and INT1 interrupt pins.
Table XXIV. TCON SFR Bit Designations
Bit
Name
Description
7
TF1
Timer 1 Overflow Flag.
Set by hardware on a timer/counter 1 overflow.
Cleared by hardware when the Program Counter (PC) vectors to the interrupt service routine.
6
TR1
Timer 1 Run Control Bit.
Set by user to turn on timer/counter 1.
Cleared by user to turn off timer/counter 1.
5
TF0
Timer 0 Overflow Flag.
Set by hardware on a timer/counter 0 overflow.
Cleared by hardware when the PC vectors to the interrupt service routine.
4
TR0
Timer 0 Run Control Bit.
Set by user to turn on timer/counter 0.
Cleared by user to turn off timer/counter 0.
3
IE1
External Interrupt 1 (
INT1) Flag.
Set by hardware by a falling edge or zero level being applied to external interrupt pin
INT1, depend-
ing on bit IT1 state.
Cleared by hardware when the when the PC vectors to the interrupt service routine only if the inter-
rupt was transition-activated. If level-activated, the external requesting source controls the
request flag, rather than the on-chip hardware.
2
IT1
External Interrupt 1 (IE1) Trigger Type.
Set by software to specify edge-sensitive detection (i.e., 1-to-0 transition).
Cleared by software to specify level-sensitive detection (i.e., zero level).
1
IE0
External Interrupt 0 (
INT0) Flag.
Set by hardware by a falling edge or zero level being applied to external interrupt pin
INT0, depend-
ing on bit IT0 state.
Cleared by hardware when the PC vectors to the interrupt service routine only if the interrupt was
transition-activated. If level-activated, the external requesting source controls the request flag,
rather than the on-chip hardware.
0
IT0
External Interrupt 0 (IE0) Trigger Type.
Set by software to specify edge-sensitive detection (i.e., 1-to-0 transition).
Cleared by software to specify level-sensitive detection (i.e., zero level).
Timer/Counter 0 and 1 Data Registers
Each timer consists of two 8-bit registers. These can be used as independent registers or combined to be a single 16-bit register
depending on the timer mode configuration.
TH0 and TL0
Timer 0 high byte and low byte.
SFR Address = 8Chex, 8Ahex respectively.
TH1 and TL1
Timer 1 high byte and low byte.
SFR Address = 8Dhex, 8Bhex respectively.
