MCXA153 VBAT (Battery-Backed Domain) Bit Mask Enumeration (VBAT電池備份域位元遮罩枚舉)

This enumeration provides bit field masks for 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. 這個枚舉提供VBAT（電池備份域）寄存器的位元欄位遮罩， 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）。

Key VBAT Components (主要VBAT組件):

• FRO16K Oscillator Control (FRO16K振盪器控制) - FROCTLA_*, FROLCKA_*, FROCLKE_*
• Version Identification (版本識別) - VERID_*
• Wakeup Source Management (喚醒源管理) - WAKEUP_WAKEUPA_*, WAKLCKA_*

Power Domain Architecture (電源域架構):

• Main Power Domain: Normal system operation (主電源域：正常系統運作)
• VBAT Domain: Battery-backed persistent operation (VBAT域：電池備份持續運作)
• Always-On Domain: Critical system functions (常開域：關鍵系統功能)

FRO16K Oscillator Features (FRO16K振盪器功能):

• 16kHz internal oscillator for low-power timing (16kHz內部振盪器用於低功耗時序)
• Battery-backed operation capability (電池備份運作能力)
• Configurable enable/disable control (可配置啟用/禁用控制)
• Lock mechanism for configuration protection (配置保護的鎖定機制)
• Clock output enable control (時鐘輸出使能控制)

Wakeup System Management (喚醒系統管理):

• Wake-up source configuration (喚醒源配置)
• Register-based wake-up control (基於寄存器的喚醒控制)
• Lock protection for wake-up settings (喚醒設定的鎖定保護)
• Persistent wake-up event storage (持續喚醒事件存儲)

Version Control System (版本控制系統):

• Feature specification tracking (功能規格追蹤)
• Minor version identification (次要版本識別)
• Major version identification (主要版本識別)
• Hardware/software compatibility verification (硬體/軟體兼容性驗證)

Usage Patterns (使用模式):

// Check if FRO16K is enabled
if (register_value & +Mask::FROCTLA_FRO_EN) {
    // FRO16K oscillator is running
}
 
// Configure wakeup register
register_value = (register_value & ~+Mask::WAKEUP_WAKEUPA_REG) |
                 (wakeup_config & +Mask::WAKEUP_WAKEUPA_REG);
 
// Lock VBAT configuration
register_value |= +Mask::WAKLCKA_LOCK;

Power Management Context (電源管理背景):

• Ultra-low power consumption design (超低功耗設計)
• Battery backup support for critical functions (關鍵功能的電池備份支援)
• Wake-up capability from deep power-down modes (從深度掉電模式的喚醒能力)
• Real-time clock and timer support (實時時鐘和定時器支援)
• Non-volatile configuration retention (非揮發性配置保持)

Security and Lock Features (安全和鎖定功能):

• Configuration lock mechanisms prevent unauthorized changes (配置鎖定機制防止未授權變更)
• Tamper detection and response capabilities (篡改檢測和響應能力)
• Secure wake-up source validation (安全喚醒源驗證)
• Protected battery domain operation (受保護的電池域運作)

註

VBAT域在主電源斷開時仍能保持關鍵功能運作，需要外部備用電池

警告

錯誤配置VBAT功能可能導致系統無法正確喚醒或功耗過高

注意

某些VBAT配置一旦鎖定就無法修改，除非進行特定的解鎖序列

VBAT Register Bit Shift Positions (VBAT寄存器位移位置)

This enumeration defines the bit shift positions for all fields within the VBAT (Battery-Backed Domain) registers of the MCXA153 microcontroller. These shift values are used for precise bit manipulation and field extraction operations in battery-backed domain register programming.
