/******************************************************************************
|
||
* 模块名称：SD2506 RTC Test Suite
|
||
* 模块功能：SD2506API-G RTC 驱动功能自测（黑盒，仅用公共 API）。
|
||
*
|
||
* 历史背景：本驱动曾出现"时间写不进"问题，根因是 sd2506.h 中寄存器宏写成
|
||
* "0x0FH"（H 后缀）。KEIL/ARMCC 不识别 H 整数后缀，将其编译为 0，
|
||
* 导致 SD2506_REG_CTR1 实际等于 0（秒寄存器），sd2506_write_enable()
|
||
* 把 WRTC 写到了错误寄存器，写保护永不解除。修正为 "0x0FU" 后恢复。
|
||
* 详见 docs/SD2506_Trap_Records.md。
|
||
*
|
||
* 当前测试：Phase 1 基本读写（init / 读 / 写 / 回读一致 / 走时），
|
||
* 结束后自动恢复板子原始时间。
|
||
* 入口：sd2506_test_run()（由 StartCh395fTestTask 经 TEST_SUITE_RTC 调度）
|
||
* 创建日期：2026-08-28
