Advanced Power Management Control Functions
The Miscellaneous Analog Control (MAC) Registers are a catch-all of registers that control and monitor a
wide variety of functions. These functions include device supervisory features such as Brown-Out and
power saving configuration, general purpose input/output configuration and interfacing, internal
temperature sensor control and current sharing control.
The MAC module also provides trim signals to the oscillator and AFE blocks. These controls are usually
used at the time of trimming at IC manufacturing; therefore this document will not cover these trim
controls.
Please note that despite the name “Miscellaneous Analog Control”, the MAC module does not only control
analog functions.
All the MAC registers and peripherals are available in the UCD3138RGC (64 pin version). The
UCD3138RHA (40 pin version) device may have reduced resources. Consult device datasheet for details.
