7:6 VGAIN_SEL Select output voltage multiplication factor: G (EEPROM bits): RW 0x0
when 00: x1
when 01: x1
when 10: x2
when 11: x3

5 ILMAX Select maximum load current: RW 0
when 0: 1.0 A
when 1: > 1.5 A
4:2 TSTEP Time step: when changing the output voltage, the new value is reached RW 0x3
through successive 12.5 mV voltage steps (if not bypassed). The
equivalent programmable slew rate of the output voltage is then:
TSTEP[2:0] = 000: step duration is 0, step function is bypassed
TSTEP[2:0] = 001: 12.5 mV/µs (sampling 3 Mhz)
TSTEP[2:0] = 010: 9.4 mV/µs (sampling 3 Mhz × 3/4)
TSTEP[2:0] = 011: 7.5 mV/µs (sampling 3 Mhz × 3/5) (default)
TSTEP[2:0] = 100: 6.25 mV/µs(sampling 3 Mhz/2)
TSTEP[2:0] = 101: 4.7 mV/µs(sampling 3 Mhz/3)
TSTEP[2:0] = 110: 3.12 mV/µs(sampling 3 Mhz/4)
TSTEP[2:0] = 111: 2.5 mV/µs(sampling 3 Mhz/5)
1:0 ST Supply state (EEPROM bits): RW 0x0
ST[1:0] = 00: Off
ST[1:0] = 01: On, high-power mode
ST[1:0] = 10: Off
ST[1:0] = 11: On, low-power mode
