PN7150：间歇性出现 DISCOVERY_FAILED (0x60 07) 错误，且使用 FeliCa Lite‑S (RC‑S966) 时 NDEF 数据被清零

您好，我正在使用PN7150读卡器IC，并观察到FeliCa Lite‑S (RC‑S966)标签存在不稳定行为。

即使将标签直接贴在天线上，我也会看到以下重复循环：

正确的UID帧
正确的 NDEF 帧
归零 NDEF 帧
空的 NDEF 帧
0x60 07（发现失败）通知

CAN 日志示例：

UID (C040041): 01 2E 54 F7 C3 59 42 3E (始终稳定)
NDEF (C060041)：有时正确：D1 01 09 54 02 65 6E 48 / 65 6C 6C 6F 21；有时为零：00 00 00 00 00 00 00 00 / 00 00 00 00 00；有时为空 (DLC=0)

当标签稍远一些（仍在正常的 NFC 范围内）时，PN7150 会频繁报告 0x60 07 并重新开始发现。

我的问题是：

当 Lite‑S 暂时禁用轮询或射频场较弱时，PN7150 是否预期会报告 0x60 07？
禁用轮询是否会导致 PN7150 返回零或空的 NDEF 数据？
对于 PN7150 固件中的 Lite-S 轮询禁用行为，是否有推荐的处理方法？
- 例如，跳过存在性检查、延迟发现重启、重试策略
是否有专门针对 FeliCa Lite‑S 行为的 PN7150 应用笔记？
