ORD PACKET
(ID = 00H)
The FLEX
protocol allows systems to transmit time
information using block information words. The information
carried in a BIW depends on the BIW word format
(Table 58). The first BIW of each phase, carrying
information about the frame structure, is used internally by
the PCD5013 and is never transmitted to the host with the
exception of the system collapse which is sent to the host
when the PCD5013 is in manual collapse mode.
The PCD5013 can be configured to send all time and date
BIWs (BIW001, BIW010 and BIW101) to the host by
setting the SBI bit in the control packet, see Section 8.4.7.
All block information words 2-4 can be optionally sent to
the host by setting the ABI bit in the roaming control
packet. When the SBI or ABI bit is set and a BIW is
received with an uncorrectable number of bit errors, the
PCD5013 sends the BIW to the host indicating that the
codeword was received in error (regardless of the BIW
word format). The PCD5013 does not support decoding of
vector and message words associated with the
data/system message BIW101.
System providers supporting local time transmissions are
required to transmit at least one time related BIW in each
phase transmitted in frame 0, cycle 0. The time
transmitted is the local time for the transmitted time zone
and refers to the actual time at the leading edge of the first
bit of sync 1 of frame 0 of the current cycle. See Tables 58,
59, and 60 and the following bit definitions of the time
related BIWs.
e:
error (Table 58). Set if more than 2-bit errors are
detected in the word or if the check character calculation
fails after error correction has been performed.
p:
phase (Table 58), is the phase on which the BIW was
found (0 = A, 1 = B, 2 = C and 3 = D).
x:
unused bits (Table 58). Their value is not guaranteed.
f:
word format type (Table 58). The value of these bits
modify the meaning of the s bits in this packet as described
in Table 59.
s:
BIW information bits (Table 58). The definition of these
bits depend on the f bits in this packet.
