TIMEBASE
0x1F
RW
Time Base
Set time base used for ADC warm up sequence according to the HFPERCLK frequency. The time base is defined as a number of
HFPERCLK cycles which should be set equal to or higher than 1us.
Value
TIMEBASE
Description
ADC warm-up is set to TIMEBASE+1 HFPERCLK clock cycles and bandgap
warm-up is set to 5x(TIMEBASE+1) HFPERCLK cycles.
