3.4 MAIN CLOCK CONTROLLER (MCC)
The MCC block supplies the clock for the ST7
CPU and its internal peripherals. It allows the
SLOW power saving mode and the Motor Contral
and SPI peripheral clocks to be managed inde-
pendently. The MCC functionality is controlled by
two bits of the MISCR register: SMS and XT16.
The XT16 bit acts on the clock of the motor control
and SPI peripherals while the SMS bit acts on the
CPU and the other peripherals.
