7.4. Timer2 

Timer2 is a 16-bit timer and it has the following features: 

- 16-bit up-counting timer/counter. 
- Automatic re-load counter. 
- 8-level prescaler. 
- Interrupt on overflow from $FFFF to $0000. 

The following is a simplified Timer2 block diagram.

The Timer2 provides the following functions: 

- Programmable interval timer function. 
- Read counter value. 

7.5. Timer2 Configuration and Operation 

Timer2 consists of a 16-bit write-only timer load register 
(TL2L, TL2ML, TL2MH, TL2H) and a 16-bit read-only timer 
counter (TC2L, TC2ML, TC2MH, TC2H). Each of them has 
low-order digits and high-order digits. Writing data into the 
timer load register (TL2L, TL2ML, TL2MH, TL2H) can 
initialize the timer counter. 

The low-order digit should be written first, and then the 
high-order digit. The timer counter is automatically loaded with 
the contents of the load register when the high order digit is 
written or the counter counts overflow from $FFFF to $0000. 
Timer Load Register: Since the register H controls the 
physical READ and WRITE operations. 
Please follow these steps: 
Write Operation: 
 

Low nibble first 

 

High nibble to update the counter 

Read Operation: 
 

High nibble first 

 

Low nibble followed.

7.6. Timer2 Control Register 

The Timer2 can be programmed in several different modes: timer, external event counter, and external trigger timer and pulse 
width measurement.
