◆ Mask

enum struct mcxa153::chip::ostimer::Mask : uint32
strong

OSTIMER (On-chip System Timer) Register Bit Masks.

Enumeration defining bit field masks for OSTIMER (On-chip System Timer) peripheral registers. The OSTIMER provides a 64-bit timer with match and capture capabilities for system timing operations. Each mask value corresponds to specific bit fields within the OSTIMER register map.

OSTIMER支援64位元計時器功能，具有匹配和捕獲能力，用於系統計時操作。 每個遮罩值對應於OSTIMER暫存器映射中的特定位元欄位。

註
All mask values are defined as 32-bit unsigned integers
Use with bitwise operations (|, &, ^, ~) for register manipulation

OSEVENT_CTRL_OSTIMER_INTRFLAG 

OSEVENT_CTRL Register - Interrupt Flag Bit.

Bit mask for the OSTIMER interrupt flag status bit. This bit indicates when a timer match event has occurred. Write 1 to clear the interrupt flag.

OSTIMER中斷標誌狀態位元遮罩

  • Register: OSEVENT_CTRL
  • Bit: [0]
  • Access: Read/Write (Write 1 to clear)
  • Reset Value: 0b0
註
Writing 1 clears the interrupt flag
Reading returns current interrupt status
OSEVENT_CTRL_OSTIMER_INTENA 

OSEVENT_CTRL Register - Interrupt Enable Bit.

Bit mask for enabling/disabling OSTIMER interrupts and wake-up requests. Controls whether the timer can generate interrupt signals to the processor.

Bit mask for the match register write ready status. Indicates when the MATCH registers are ready to accept new write operations.

匹配暫存器寫入就緒狀態遮罩

  • Register: OSEVENT_CTRL
  • Bit: [2]
  • Access: Read-Only
  • Reset Value: 0b1
傳回值
0b0MATCH registers are not ready for write (write operation in progress)
0b1MATCH registers are ready for new write operations

◆ Shift

enum struct mcxa153::chip::ostimer::Shift : uint32
strong

OSTIMER (On-chip System Timer) Register Bit Shift Positions.

Enumeration defining bit shift positions for accessing specific bit fields within OSTIMER peripheral registers. These shift values are used in conjunction with bit masks to extract or set individual bit fields in the registers.

OSTIMER周邊暫存器位元位移位置列舉，用於存取暫存器中特定位元欄位。 這些位移值與位元遮罩配合使用，以提取或設定暫存器中的個別位元欄位。

  • Used with bitwise shift operations (<<, >>) for bit field manipulation
  • Combined with masks for register read/write operations
  • All values represent bit positions within 32-bit registers
  • Shift positions are zero-based (0 = LSB, 31 = MSB)
註
Use these values with corresponding masks from Mask.h
Example: (register_value >> shift_position) & field_mask
