詳細描述

OSTIMER (On-chip System Timer) Peripheral Register Structure.

Memory-mapped register structure for accessing OSTIMER peripheral registers. The OSTIMER provides a 64-bit system timer with match and capture capabilities for precise timing operations and system scheduling.

OSTIMER周邊暫存器結構體，提供64位元系統計時器功能，具有匹配和捕獲能力，用於精確計時操作和系統排程。

Base Address: Varies by implementation (typically in memory map)
Register Width: 32-bit aligned
Timer Resolution: 64-bit (42-bit effective)
Supports: Match interrupts, Capture events, Debug control

註: All register accesses should be aligned to 32-bit boundaries; Some registers are read-only, others are read-write

自: v1.0.0

資料成員說明文件

◆ capture_h

__I uint32 mcxa153::chip::ostimer::Register::capture_h

Capture High Register (10-bit effective)

Upper portion of captured timer value (only lower 10 bits valid). Combined with capture_l provides complete captured timer value.

捕獲計時器值的高位元部分（僅低10位元有效）

Offset: 0xC
Access: Read-Only (__I)
Width: 32-bit (only [9:0] bits used)
Reset: 0x00000000
Valid Range: 0x000 - 0x3FF

註: Only bits [9:0] contain valid captured data; Must be read together with capture_l for complete value

◆ capture_l

__I uint32 mcxa153::chip::ostimer::Register::capture_l

Capture Low Register (32-bit)

Lower 32-bit portion of captured timer value. Captures the current timer count when a capture event occurs.

捕獲計時器值的低32位元部分

Offset: 0x8
Access: Read-Only (__I)
Width: 32-bit
Reset: 0x00000000

註: Capture events can be triggered by external signals or software; Value represents timer state at moment of capture

◆ evtimerh

__I uint32 mcxa153::chip::ostimer::Register::evtimerh

Event Timer High Register (10-bit effective)

Upper portion of the 64-bit OSTIMER counter (only lower 10 bits valid). When combined with evtimerl, provides the complete timer count.

64位元OSTIMER計數器的高位元部分（僅低10位元有效）

Offset: 0x4
Access: Read-Only (__I)
Width: 32-bit (only [9:0] bits used)
Reset: 0x00000000
Valid Range: 0x000 - 0x3FF

註: Only bits [9:0] contain valid timer data; Upper bits [31:10] should be ignored

◆ evtimerl

__I uint32 mcxa153::chip::ostimer::Register::evtimerl

Event Timer Low Register (32-bit)

Lower 32-bit portion of the 64-bit OSTIMER counter. Contains the current timer count value that increments continuously.

64位元OSTIMER計數器的低32位元部分

Offset: 0x0
Access: Read-Only (__I)
Width: 32-bit
Reset: 0x00000000

註: Combined with evtimerh to form complete 42-bit timer value; Reads are atomic and represent instantaneous timer value

◆ match_h

__IO uint32 mcxa153::chip::ostimer::Register::match_h

Match High Register (10-bit effective)

Upper portion of timer match value (only lower 10 bits valid). Combined with match_l defines complete match compare value.

計時器匹配值的高位元部分（僅低10位元有效）

Offset: 0x14
Access: Read/Write (__IO)
Width: 32-bit (only [9:0] bits used)
Reset: 0x000003FF
Valid Range: 0x000 - 0x3FF

註: Only bits [9:0] should be written/are valid; Must be programmed together with match_l

◆ match_l

__IO uint32 mcxa153::chip::ostimer::Register::match_l

Match Low Register (32-bit)

Lower 32-bit portion of timer match value. When timer reaches this value (combined with match_h), generates match event.

計時器匹配值的低32位元部分

Offset: 0x10
Access: Read/Write (__IO)
Width: 32-bit
Reset: 0xFFFFFFFF

註: Check OSEVENT_CTRL.MATCH_WR_RDY before writing; Match events can trigger interrupts if enabled

◆ osevent_ctrl

__IO uint32 mcxa153::chip::ostimer::Register::osevent_ctrl

OSTIMER Event Control Register.

Control and status register for OSTIMER events, interrupts, and configuration. Contains interrupt flags, enable bits, write ready status, and debug control.

OSTIMER事件控制暫存器，用於中斷和配置控制

Offset: 0x1C
Access: Read/Write (__IO)
Width: 32-bit
Reset: 0x00000004 (MATCH_WR_RDY = 1)

Bit Fields:

[0] OSTIMER_INTRFLAG: Interrupt flag (write 1 to clear)
[1] OSTIMER_INTENA: Interrupt enable (0=disabled, 1=enabled)
[2] MATCH_WR_RDY: Match write ready flag (read-only)
[3] DEBUG_EN: Debug enable (0=halt in debug, 1=continue in debug)
[31:4] Reserved

註: Use appropriate bit masks from Mask.h for bit manipulation

參閱: mcxa153::chip::ostimer::Mask for bit field definitions

◆ reserved0

uint8 mcxa153::chip::ostimer::Register::reserved0[4]

Reserved Space.

Reserved memory space in the register map. These bytes should not be accessed.

暫存器映射中的保留記憶體空間

Offset: 0x18-0x1B
Size: 4 bytes
Access: Should not be accessed

警告: Do not read from or write to this reserved space
