SMS Slow mode Select.
This bit is set by software and only cleared by hardware after a reset. If this
bit is set, it enables the use of an internal divide-by-2 clock divider (refer to
Figure 18 on page
0: Divide-by-2 disabled and CPU clock frequency is standard
1: Divide-by-2 enabled and CPU clock frequency is halved.
USBOE USB enable.
If this bit is set, the port PC2 (PB1 on SO24) outputs the USB output enable
signal (at “1” when the ST7 USB is transmitting data).
Unused bits 7-4 are set.
MCO Main Clock Out selection
This bit enables the MCO alternate function on the PA0 I/O port. It is set and
cleared by software.
0: MCO alternate function disabled (I/O pin free for general-purpose I/O)
