Low-Level Register Access

The MAX4455 registers can be accessed directly in

expert mode, which is enabled by clicking the Expert

Mode button (

) (see Table 2).

Normally, the user interface automatically writes to

affected registers as soon as a control is changed. If

you check “postpone automatic updates,” you can

set up a write operation and control the exact moment

when the register is updated. For example, you can

type “150” into the VOFFSET edit field, and then click

the VOFFSET SET button to perform the write.
