Bit 2 = CLKDIV Clock Divider .
This bit is set by software and only cleared by hard-
ware after a reset. If this bit is set, it enables the use
of a 12 MHz external oscillator (refer to
on page
0: 24 MHz external oscillator
1: 12 MHz external oscillator.
Bit 1 = USBOE USB enable.
If this bit is set, the port PC2 outputs the USB out-
put enable signal (at “1” when the ST7 USB is
transmitting data).
Unused bits 7-4 are set.
Bit 0 = 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.
