SWRS037B – JANUARY 2006 – REVISED MARCH 2015

The default value for GDO0 is a 125 to 146 kHz clock output (XOSC frequency divided by 192). Because
the XOSC is turned on at power-on-reset, this can be used to clock the MCU in systems with only one
crystal. When the MCU is up and running it can change the clock frequency by writing to
IOCFG0.GDO0_CFG.

An on-chip analog temperature sensor is enabled by writing the value 128 (0x80h) to the
IOCFG0.GDO0_CFG register. The voltage on the GDO0 pin is then proportional to temperature. See

Section 4.9

for temperature sensor specifications.
