Question
Mention the roll over value (in hex and decimal) of the timer for each of the following cases:1. Timer 0 Normal mode2. Timer 1 normal mode
Solution
-
Timer 0 Normal Mode:
- The Timer 0 is an 8-bit register. Therefore, it can count from 0 to 255. When it reaches its maximum value (255), it rolls over back to 0.
- In hexadecimal, the maximum value is FF.
-
Timer 1 Normal Mode:
- The Timer 1 is a 16-bit register. Therefore, it can count from 0 to 65535. When it reaches its maximum value (65535), it rolls over back to 0.
- In hexadecimal, the maximum value is FFFF.
