11.3.2
MTIM Clock Configuration Register (MTIMCLK)
MTIMCLK contains the clock select bits (CLKS) and the prescaler select bits (PS).
11.3.3
MTIM Counter Register (MTIMCNT)
MTIMCNT is the read-only value of the current MTIM count of the 8-bit counter.

Description
5:4
CLKS
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.
00
Encoding 0 — Bus clock (BUSCLK).
01
Encoding 1 — Fixed-frequency clock (XCLK).
10
Encoding 3 — External source (TCLK pin), falling edge.
11
Encoding 4 — External source (TCLK pin), rising edge.
3:0
PS
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.
