Description

System oscillator control

Fields

BYPASS

Bypass system oscillator

0 (OSCILLATOR_IS_NOT_BY): Oscillator is not bypassed.

1 (BYPASS_ENABLED_PLL_): Bypass enabled. PLL input (sys_osc_clk) is fed directly from the XTALIN pin bypassing the oscillator. Use this mode when using an external clock source instead of the crystal oscillator.

FREQRANGE

Determines frequency range for Low-power oscillator.

0 (1__20_MHZ_FREQUENCY): 1 - 20 MHz frequency range.

1 (15__25_MHZ_FREQUENC): 15 - 25 MHz frequency range
