The content in this register reflects the International bits, Remote Alarm Indication bit and National bits. The Si[1:0] bits are the International bits.
Note that the contents of this register are not updated while the received data stream is out of Basic Frame.
Directly reflect the content in the International bit in the latest received FAS frame and is updated on the generation of the IFPI interrupt on FAS
Directly reflect the content in the International bit in the latest received NFAS frame and is updated on the generation of the IFPI interrupt on
Directly reflect the content in the Remote Alarm Indication (A) bit in the latest received NFAS frame and is updated on the generation of the IFPI
Directly reflect the content in the National bit in the latest received NFAS frame and is updated on the generation of the IFPI interrupt on NFAS
The CRCERR[7:0], together with the CRCERR[9:8], represent the number of the CRC errors and update every second. The CRCERR[0] is the
