In the current implementation, the HAL_PWR_EnableSleepOnExit function is used, but GPIO states are not explicitly frozen.
Implementing these "Better" ULP bases yields the following projected improvements (based on STM32L4/Illuminatus specs): 2912025ulpbaseseviluminatustxt better

In online spaces — especially forums, encrypted chats, or puzzle communities — users sometimes share seemingly random strings of letters and numbers. These could be: reduce wake-up latency jitter
The wake-up latency is currently dominated by the time required to stabilize the PLL.
The existing ULP base implementation relies on standard library calls for entering low-power modes. Preliminary analysis of the ev_illuminatus configuration identifies three critical bottlenecks:
This report details the analysis of the current Ultra-Low Power (ULP) base implementation within the EV-Illuminatus environment. The current baseline, while functional, exhibits higher than expected current consumption in Standby and Shutdown modes. This document proposes "Better" optimization strategies to extend battery life, reduce wake-up latency jitter, and improve overall power budget efficiency.
