Stopping Clock Output

If the BUSCLK pin is not in use, output on the pin from the R-IN32M4-CL3 can be stopped. See Section 4.2.2 "Clock
Control Registers (CLKGTD0, CLKGTD1, CLKGTD2)" in the "R-IN32M4-CL3 User's Manual: Hardware edition"
regarding control of the GCBCLK bit in the CLKGTD1 register, which enables or disables output from the BUSCLK
pin.
