Note 1

If register BUCK<x>_MODE = 10 (synchronous) then the buck operates in PFM mode for

VBUCK < 0.7 V. For complete control of the buck mode (PWM versus PFM) use BUCK<x>_MODE = 00.

Note 2

Minimum tolerance 35 mV.

Note 3

Generated from internal 6 MHz oscillator and can be adjusted by ±10 % via register OSC_FRQ, see

Section 8.14.
