Bit Field Value Description
31-18 Reserved 0 Reads return 0. Writes have no effect.
17-16 CCDIV Counter Clock Divider
CCDIV determines the ratio between the counter clock and VCLK2.
0 CCLK = VCLK2
1h CCLK = VCLK2 / 2
2h CCLK = VCLK2 / 3
3h CCLK = VCLK2 / 4
15-10 Reserved 0 Reads return 0. Writes have no effect.
