Bit 7
Timer 1 Overflow Flag. This bit indicates when Timer 1 overflows its
maximum count as defined by the current mode. 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.
Bit 6
0 = Timer 1 is halted.
1 = Timer 1 is enabled.
TF0
Bit 5
Timer 0 Overflow Flag. This bit indicates when Timer 0 overflows its
maximum count as defined by the current mode. This bit can be cleared by
software and is automatically cleared when the CPU vectors to the Timer 0
interrupt service routine or by software.
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.
Bit 4
0 = Timer 0 is halted.
1 = Timer 0 is enabled.
IE1
Bit 3
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 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
Bit 2
or level triggered interrupts.
0 = INT1 is level triggered.
1 = INT1 is edge triggered.
IE0
Bit 1
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 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
Bit 0
or level triggered interrupts.
0 = INT0 is level triggered.
1 = INT0 is edge triggered.
