12.11.12 CNTH - Counter Register H
12.11.13 CNTL - Counter Register L
12.11.14 PERH - Period Register H
8210B–AVR–04/10
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 write access has priority over count, clear, or
reload of the counter.
For more details on reading and writing 16-bit register refer to
page
• 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.
