(BIW)
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 49). The first BIW of each phase, carrying
information about the frame structure, is used internally by
the PCD5008 and is never transmitted to the host.
The PCD5008 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.
When the SBI bit is set and a BIW is received with an
uncorrectable number of bit errors, the PCD5008 sends
the BIW to the host indicating that the codeword was
received in error (regardless of the BIW word format).
The PCD5008 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 50, 51, 52 and 53 and the following bit
definitions of the time related BIWs.
e:
error (Table 49). 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 49), is the phase on which the BIW was
found (0 = A, 1 = B, 2 = C and 3 = D).
x:
unused bits (Table 49). Their value is not guaranteed.
f:
word format type (Table 49). The value of these bits
modify the meaning of the s bits in this packet as described
in Tables 50, 51 and 52. If the e bit is not set, this field is
one of 001, 010 or 101.
s:
BIW information bits (Table 49). The definition of these
bits depend on the f bits in this packet.
m:
month field (Table 50). 0001 to 1100 binary
correspond to January to December in month order.
d:
day field (Table 50). 00001 to 11111 binary correspond
to 1 to 31 days in the month.
