TCON.0 IT0
Interrupt request flag for external interrupt 0.
The bit is reset automatically when an interrupt is serviced.
The bit can be set and reset by software when IT0 = "1".
TCON.1 IE0
External interrupt 1 signal is used in level detect mode when this bit is "0", and in
trigger detect mode when "1".
TCON.2 IT1
Interrupt request flag for external interrupt 1.
The bit is reset automatically when an interrupt is serviced.
The bit can be set and reset by software when IT1 = "1".
TCON.3 IE1
Counting start and stop control bit for timer/counter 0.
Timer/counter 0 starts counting when this bit is "1", and stops counitng when "0".
TCON.4 TR0
Interrupt request flag for timer interrupt 0.
The bit is reset automatically when an interrupt is serviced.
The bit is set to "1" when a carry signal is generated from timer/counter 0.
TCON.5 TF0
Counting start and stop control bit for timer/counter 1.
The timer/counter 1 starts counting when this bit is "1", and stops counting when "0".
TCON.6 TR1
Interrupt request flag for timer interrupt 1.
The bit is reset automatically when interrupt is serviced.
The bit is set to "1" when carry signal is generated from timer/counter 1.
