Clock Source Select — These two read/write bits select one of four different clock sources as the input to the
MTIM prescaler. Changing the clock source while the counter is active does not clear the counter. The count
continues with the new clock source. Reset clears CLKS to 00.

Clock Source Prescaler — These four read/write bits select one of nine outputs from the 8-bit prescaler.
Changing the prescaler value while the counter is active does not clear the counter. The count continues with the
new prescaler value. Reset clears PS to 0000.
0000 Encoding 0 — MTIM clock source ÷ 1.
0001 Encoding 1 — MTIM clock source ÷ 2.
0010 Encoding 2 — MTIM clock source ÷ 4.
0011 Encoding 3 — MTIM clock source ÷ 8.
0100 Encoding 4 — MTIM clock source ÷ 16.
0101 Encoding 5 — MTIM clock source ÷ 32.
0110 Encoding 6 — MTIM clock source ÷ 64.
0111 Encoding 7 — MTIM clock source ÷ 128.
1000 Encoding 8 — MTIM clock source ÷ 256.
All other encodings default to MTIM clock source ÷ 256.
Encoding 0 — Bus clock (BUSCLK).
Encoding 1 — Fixed-frequency clock (XCLK).
Encoding 3 — External source (TCLK pin), falling edge.
Encoding 4 — External source (TCLK pin), rising edge.
