3307B–USB–4/04
Timer/Counter0 Control Register – TCCR0
Bits 7..3 –Res: Reserved Bits
These bits are reserved bits in the AT43USB355 and always read as zero.
Bits 2, 1, 0 – CS02, CS01, CS00: Clock Select0, bit 2, 1 and 0
The Clock Select0 bits 2, 1 and 0 define the prescaling source of Timer/Counter0.
The Stop condition provides a Timer Enable/Disable function. The CK down divided modes
are scaled directly from the CK 12 MHz clock.
Timer/Counter0 – TCNT0
The Timer/Counter0 is realized as an up-counter with read and write access. If the
Timer/Counter0 is written and a clock source is present, the Timer/Counter0 continues count-
ing in the clock cycle following the write operation.
