Enable MIR_CLK divider.
External clock source select.
0 - Use the external XTALI clock input as the clock source.
1 - Use one of the internal PLLs selected by PSEL as the
clock source.
PLL source select.
1 - Select PLL2 as the clock source.
0 - Select PLL1 as the clock source.
Pre-divider value. Generates divide by 2, 2.5, or 3 from the
clock source.
00 - Disable clock
01 - Divide-by-2
10 - Divide-by-2.5
11 - Divide-by-3
MIR_CLK divider value. Forms a divide-by-N of the pre-
divide clock output. MIR_CLK is the source clock divided
by PDIV divided by N.
