14.12.12 CNTH - Counter Register H
14.12.13 CNTL - Counter Register L
14.12.14 PERH - Period Register H
8077H–AVR–12/09
For more details refer to
The CNTH and CNTL register pair represents the 16-bit value CNT. CNT contains the 16-bit
counter value in the Timer/Counter. The CPU and DMA write access has priority over count,
clear, or reload of the counter.

• Bit 7:0 - CNT[15:8]
These bits holds the 8 MSB of the 16-bit Counter register.
• Bit 7:0 - CNT[7:0]
These bits holds the 8 LSB of the 16-bit Counter register.
The PERH and PERL register pair represents the 16-bit value PER. PER contains the 16-bit
TOP value in the Timer/Counter.
• Bit 7:0 - PER[15:8]
These bits holds the 8 MSB of the 16-bit Period register.
