1 Working mode 0 When
the timer / counter T0 works in mode 0, only 13 bits of the 16-bit counter are used, namely the upper 8 bits of TH0 and the lower 5 bits of TL0, forming a 13-bit timer /counter.
1) Working in timing mode
2) Working in counting mode
2 Working mode 1
Timer T0 Working mode 1 is similar to working mode 0, the difference lies in the number of bits of the counter. Working mode 0 uses a 13-bit counter to participate in counting, while working mode 1 uses a 16-bit counter to participate in counting.
1) Working in timing mode
2) Working in counting mode
Working mode 1 is a 16-bit counter. This is the only difference between working mode 1 and working mode 0 in counting mode.
3 Working mode 2
When the timer T0 is in working mode 2, the 16-bit counter is divided into two independent 8-bit counters TH0 and TL0.
1) Working in timing mode
2) Working in counting mode
The difference between working mode 2 and working mode 0 and mode 1 is that working mode 2 is an 8-bit counter.
4 Working mode 3
Working mode 3 is only valid for timer T0. When timer T0 works in mode 3, the 16-bit counter is divided into two independent 8-bit counters TH0 and TL0.
When timer T0 works in mode 3, timer T1 can only work in modes 0 to 2 and work in situations where interrupts are not required.
