22.11.2 TCNT2 – Timer/Counter Register

Name: TCNT2

Offset: 0x24 [ID-00000312]

Reset: 0x00

Property: When addressing I/O Registers as data space the offset address is 0x44

When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When

addressing I/O Registers as data space using LD and ST instructions, 0x20 must be added to these offset

addresses.

The Timer/Counter Register gives direct access, both for read and write operations, to the Timer/Counter

unit 8-bit counter. Writing to the TCNT2 Register blocks (removes) the Compare Match on the following

timer clock. Modifying the counter (TCNT2) while the counter is running, introduces a risk of missing a

Compare Match between TCNT2 and the OCR2 Register.
