Product specification

PCD5013

8.4.13 ROAMING STATUS PACKET (ID = 60H)

The PCD5013 automatically prompts the host to read a

Roaming Status Packet if RSR, MS1, MFI, MS2, MBI,

MAW, NBU, NDR 1, NDR 0, or SCU is set.

RSR: re-synchronization signal received (Table 19).

Set when the PCD5013 detected a re-synchronization

signal (Ar/Ar) and the host configured the PCD5013 to

ignore it via the IRS bit in the roaming control packet. This

bit is cleared when read.

MS1: missed synchronization 1 (Table 19). Set when the

PCD5013 fails to detect the first synchronization pattern

(A/A) of a FLEX™ frame and the PCD5013 was configured

to report missed frame information via the MFC bit in the

roaming control packet. This bit is cleared when read.

MFI: missed frame information word (Table 19). Set when

the frame information word is received with an

uncorrectable number of errors and the PCD5013 was

configured to report missed frame information via the MFC

bit in the roaming control packet. This bit is cleared when

read.

MS2: missed synchronization 2 (Table 19). Set when the

PCD5013 failed to detect the second synchronization

pattern (C/C) of a frame and PCD5013 was configured to

report missed frame information via the MFC bit in the

roaming control packet. This bit is cleared when read.

MBI: missed block information word 1 (Table 19).

Set when at least one of the block information word ones

is received with an uncorrectable number of errors and

PCD5013 was configured to report missed frame

information via the MFC bit in the roaming control packet.

This bit is set no more than once per frame regardless of

the number of missed block information word 1’s in the

frame. This bit is cleared when read.

MAW: missed address word (Table 19). Set when any

address words in the address field is received with an

uncorrectable number of errors and PCD5013 was

configured to report missed frame information via the MFC

bit in the roaming control packet. This bit is set no more

than once per frame regardless of the number of missed

address words in the frame. This bit is cleared when read.

NBU: network bit update (Table 19). Set when the NBC bit

in the roaming control packet is set and a frame

information word is received with a correctable number of

errors. This bit is not set when the frame information word

is not received due to missing the first synchronization

pattern (A/A). This bit is cleared when read.

n: network bit value (Table 19). When NBU is set, this is

the value of the n bit in the last received frame information

word.

NDR: noise detect result (Tables 18 and 19). These bits

indicate the result of a noise detect. The results of noise

detects initiated by setting the SND bit in the roaming

control packet is always reported. The results of the

automatic noise detects performed in asynchronous mode

is only reported if the RND bit is set in the roaming control

packet. When continuous noise detects during block data

are enabled by setting the CND bit in the roaming control

packet, only the ‘No FLEX™ signal detected’ result is

reported. These bits are cleared when read.

SCU: system collapse update (Table 19). Set when the

PCD5013 is configured for manual collapse mode by

setting the MCM bit in the roaming control packet and the

system collapse of a frame is received. This bit is set no

more than once per frame regardless of the number of

phases in the frame. This bit is not set in frames in which

no block information word 1’s is received properly. This bit

is cleared when read.

RSC: received system collapse (Table 19). When SCU is

set, this value represents the system collapse value that

was received in the frame.
