Field
VALUE
Description
This value is the number of system clock cycle needed for the conversion time.(ADC 0)
13.10.17 Cross triggering unit expected value B (CTU_EXP_B)
This register is used to configure the number of the expected clock cycles needed for the conversion time
of ADC_1. Please refer Section 13.9, Conversion time evaluate for more details.

Description
This value is the number of system clock cycle needed for the conversion time.(ADC 1)
13.10.18 Cross triggering unit counter range (CTU_CNTRNG)
This register is used to mask the less significant bits in the expected clock cycles (i.e. CTU_EXP_A and
CTU_EXP_B). In this way it is possible to define an acceptance range around these values.Please refer
Section 13.9, Conversion time evaluate for more details
