In mode0, the 12-bit register of timer0 consists of 7-bit of TH0 and the lower 5-bit of TL0. The
higher 1-bit of TH0 and higher 3-bit of TL0 are disregarded. When this 12-bit register is
overflowed, set TF0 to ‘1’. The operation of timer1 is same as that of timer0.
TMOD (TIMER MODE CONTROL REGISTER, 0x89)
TL0/TL1/TH0/TH1 (TIMER REGISTERS, 0x8A, 0x8B, 0x8C, 0x8D)
Two pairs of registers, (TH0, TL0) and (TH1, TL1), can be used as 16-bit timer register for Timer0 and
Timer1 or can be used as 8-bit register respectively.

External Interrupt1 Type Control: This field specifies the type of
External interrupt1.
External Interrupt0 Edge Flag: When this field is ‘1’, External
interrupt0 is pending. After the interrupt service routine is executed,
this field is cleared by hardware.
External Interrupt0 Type Control: This field specifies the type of
External interrupt1.
Timer Gate Control: When TR1 is set to ‘1’ and GATE1 is ‘1’,
Timer1 is enabled while INT1 pin is in high. When GATE1 is set to
‘0’ and TR1 is set to ‘1’, Timer1 is enabled
Timer1 Counter Mode Select: When this field is set to ‘1’, Timer1
is enabled as counter mode.
Timer1 mode select:.
Timer0 Gate Control: When TR0 is set to ‘1’ and GATE0 is ‘1’,
Timer0 is enabled while INT0 pin is in high. When GATE1 is set to
‘0’ and TR1 is set to ‘1’, Timer0 is enabled
When this field is set to ‘1’, Timer0 is enabled as counter mode.

1 = Edge type. When the falling edge of INT1 is detected, the
interrupt occurs.
0 = Level type. When INT1 is low, the interrupt occurs.
