Figure 16-2. Timer/Counter1 Synchronization Register Block Diagram.
Many register and bit references in this section are written in general form. A lower case “n”
replaces the Timer/Counter number, in this case 0. A lower case “x” replaces the Output Com-
pare Unit, in this case Compare Unit A, B, C or D. However, when using the register or bit
defines in a program, the precise form must be used, i.e., TCNT1 for accessing Timer/Counter1
counter value and so on. The definitions in

The counter reaches the BOTTOM when it becomes 0.
The counter reaches its MAXimum value when it becomes 0x3FF (decimal 1023).
The counter reaches the TOP value (stored in the OCR1C) when it becomes equal to the
highest value in the count sequence. The TOP has a value 0x0FF as default after reset.
