ACMP LAD addressOffset = 0x004

This register enables and controls the voltage ladder. The fraction of the reference voltage produced by the ladder is programmable in steps of 1/31.

Table 1. ACMP registerName = LAD addressOffset = 0x004
Bit Symbol Value Description Reset value
0 LADEN   Voltage ladder enable 0
5:1 LADSEL   Voltage ladder value. The reference voltage Vref depends on the LADREF bit below. 00000 = V_ SS 00001 = 1 × Vref/31 00010 = 2 × Vref/31 ... 11111 = Vref 0
6 LADREF   Selects the reference voltage Vref for the voltage ladder: 0
