Bits 2 to 0—Clock Select 2B to 0B (CKSEL2B to CKSEL0B): These bits select clock ", scaled
from the internal clock source, for DCNT10G and DCNT10H in channel 10, from ', '/2, '/4,
10.2.5
The timer I/O control registers (TIOR) are 8-bit registers. The ATU has ten TIOR registers, one
for channel 0, three for channel 1, one for channel 2, two each for channels 3 and 4, and one for
channel 5.
Each TIOR is an 8-bit readable/writable register used to select the functions of dedicated input
capture registers and general registers.
For dedicated input capture registers (ICR), TIOR performs edge detection setting.
