+ * @brief @tagAPI52 Fixes for hardware-related anomalies.
+ *
+ * If you are using PCA10040 (part of nRF52 Development Kit), 
+ * you must define the macro HAL_NFC_ENGINEERING_BC_FTPAN_WORKAROUND in order to apply 
+ * workarounds for the following anomalies:
+ * - 79. NFCT: A false EVENTS_FIELDDETECTED event occurs after the field is lost.
+ * - 116. NFCT does not release HFCLK when switching from ACTIVATED to SENSE mode.
+ *
+ * If you are using PCA10056 Engineering A (part of nRF52840 Development Kit), 
+ * you must define the macro HAL_NFC_NRF52840_ENGINEERING_ABC_WORKAROUND in order to apply 
+ * workarounds for the following anomalies:
+ * - 98. NFCT: The NFCT is not able to communicate with the peer.
+ * - 116. NFCT does not release HFCLK when switching from ACTIVATED to SENSE mode.
+ * - 144. NFCT: Not optimal NFC performance
+ *
+ * If you are using PCA10056 Engineering B or C (part of nRF52840 Development Kit), 
+ * you must define the macro HAL_NFC_NRF52840_ENGINEERING_ABC_WORKAROUND in order to apply 
+ * workarounds for the following anomalies:
+ * - 190. NFCT: Event FIELDDETECTED may be generated too early.
+ *
+ * The use of implemented workarounds for PCA10056 are determined at the runtime and depends 
+ * on the chip variant.
+ *
+ * The current code contains a patch for anomaly 25 (NFCT: Reset value of 
+ * SENSRES register is incorrect), so that it now works on Windows Phone.
