MCLKDIS MCLKDIV2 — RATIO
Default01000000
Because clock rates must be stable when the device is powered up, the device must be powered down before changing clock rates.

0 (Default) On
1 Off. Disables the clock tree to save power when the device is powered down. Set only after the device powers down.
6 MCLKDIV2 MCLK divide by 2. Configures a divide between the input pin MCLK and the derived core clock, MCLK
INT
.
0 No divide
1 (Default) Divide by 2
