詳細描述

MCXA153 VBAT (Battery-Backed Domain) Register Structure (VBAT電池備份域寄存器結構)

This structure provides access to VBAT (Battery-Backed Domain) registers, which control low-power domain functionality that remains operational even when the main power supply is disconnected, as long as backup battery power is available. 這個結構提供VBAT（電池備份域）寄存器的存取，控制即使在主電源斷開時 仍能運作的低功耗域功能（只要有備用電池電源）。

Base Address: 0x40032000 Memory Region: Always-On Power Domain Access: Read/Write (some registers may be lock-protected)
