• Bit [2:0] - CLKM_CTRL
These register bits set clock rate of pin 17 (CLKM).
Table 9-14.
Register 0x12 (XOSC_CTRL):
The register XOSC_CTRL controls the operation of the crystal oscillator.
• Bit [7:4] - XTAL_MODE
These register bits set the operating mode of the crystal oscillator. For normal operation the
default value is set to XTAL_MODE = 0xF after reset. Using an external clock source it is recom-
mended to set XTAL_MODE = 0x4.
