MCLKCtl.7
HSOEN
High-speed oscillator enable. When set = 1, disables the high-speed
crystal oscillator and VCO/PLL system. This bit is not changed when the
PWRDN bit is set but the oscillator/VCO/PLL is disabled. The HSOEN bit
should never be set under normal circumstances. Power down control
should only be initiated via use of the PWRDN bit in MISCtl0.
MCLKCtl.6
KBEN
1 = Disable the keypad logic clock. This bit is not changed in PWRDN
mode but the function is disabled.
MCLKCtl.5
SCEN
1 = Disable the smart card logic clock. This bit is not changed in PWRDN
mode but the function is disabled. Interrupt logic for card insertion/removal
remains operable even with smart card clock disabled.
MCLKCtl.4
USBEN
1 = Disable the USB logic clock. This bit is not changed in PWRDN mode
but the function is disabled.
MCLKCtl.3
32KEN
1 = Disable the 32Khz oscillator. This function is not affected by PWRDN
mode. Note: This bit must be set if there is no 32KHz crystal. Some
internal clocks and circuits will not run if the oscillator is enabled and
no crystal is connected.
MCLKCtl.2
MCT.2
This value determines the ratio of the VCO frequency (MCLK) to the high-
speed crystal oscillator frequency such that:
MCLK = (MCount*2 + 4)*Fxtal. The default value is MCount = 2h such that
MCLK = (2*2 + 4)*12.00MHz = 96MHz.
