(80) Clock output control register (CLKOUTCON)
This register controls the clock output.
The clock can be output from the GPIO0 pin by using the clock output enable bit.
The output clock can be selected between the clock output select bit 0 and the clock output select bit 1.
CLKOUTCON register is set via serial interface in 8-bit units.
Reset signal generation sets this register to 00H.
