Bits 2, 1, and 0—Clock Select (CKS2, CKS1, and CKS0): These bits and bits ICKS1 and
ICKS0 in the serial/timer control register (STCR) select the internal or external clock source for
the timer counter. Six internal clock sources, derived by prescaling the system clock, are available
for each timer channel. For internal clock sources the counter is incremented on the falling edge of
the internal clock. For an external clock source, these bits can select whether to increment the
counter on the rising or falling edge of the clock input (TMCI), or on both edges.
