TF1: Timer 1 Overflow Flag.
Set by hardware when Timer 1 overflows. This flag can be cleared by software but is automatically
cleared when the CPU vectors to the Timer 1 interrupt service routine.
0: No Timer 1 overflow detected.
1: Timer 1 has overflowed.
TR1: Timer 1 Run Control.
0: Timer 1 disabled.
1: Timer 1 enabled.
TF0: Timer 0 Overflow Flag.
Set by hardware when Timer 0 overflows. This flag can be cleared by software but is automatically
cleared when the CPU vectors to the Timer 0 interrupt service routine.
0: No Timer 0 overflow detected.
1: Timer 0 has overflowed.
TR0: Timer 0 Run Control.
0: Timer 0 disabled.
1: Timer 0 enabled.
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 rou-
tine if IT1 = 1. This flag is the inverse of the /INT1 input signal's logic level when IT1 = 0.
IT1: Interrupt 1 Type Select.
This bit selects whether the configured /INT1 signal will detect falling edge or active-low level-sensi-
tive interrupts.
0: /INT1 is level triggered.
1: /INT1 is edge triggered.
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 rou-
tine if IT0 = 1. This flag is the inverse of the /INT0 input signal's logic level when IT0 = 0.
IT0: Interrupt 0 Type Select.
This bit selects whether the configured /INT0 signal will detect falling edge or active-low level-sensi-
tive interrupts.
0: /INT0 is level triggered.
1: /INT0 is edge triggered.
