4.14.6 Usage Hints
Voltage Level Burst
The total duration of the Voltage Level Burst measurement is a function of the system clock frequency (see Section 4.18 on
page 239) and the data sampling delay, selected by SMPDLY field in ACMTIM register. The values in Table 28 should only
be used to evaluate the maximum duration of the measurement. Actual duration may be shorter, depending on the input
level value. The software should use either EOMEV flag polling or the ACM interrupt, as described in Section 4.14.4 on
page 210.

Description
5-0
VOLTLVL (Voltage Level Data). Voltage level of the respective input i (KBSINi for i 0 through 7), while operating
in Voltage Level Burst mode (ACMMOD = 012 in ACMCNF register). The readout is an unsigned value with
1 LSB = VCC/64; the input voltage is calculated as: VIN = VOLTVL * (VCC/64).
