22.1.6.5
Row 25 data contents
The Hamming error flags are set if the on-board
8/4 Hamming checker detects that there has been an
uncorrectable (2-bit) error in the associated byte. It is
possible for the page to still be acquired if some of the
page address information contains uncorrectable errors if
that part of the page request was a ‘Don’t Care’. There is
no error flag for the magazine number because an
uncorrectable error in this information prevents the page
being acquired.
The interrupt sequence (C9) bit is automatically dealt with
by the acquisition section, so that rolling headers do not
contain a discontinuity in the page number sequence.
The magazine serial bit (C11) indicates whether the
magazine transmission is serial or parallel. This affects
how the acquisition section operates and is dealt with
automatically.
The newsflash (C5), subtitle (C6), suppress header (C7),
inhibit display (C10) and language control (C12 to 14) bits
are dealt with automatically by the display section.
The update bit (C8) has no effect on the hardware. The
remaining 32 bytes of the page header are parity checked
and written into columns 8 to 39 of row 0. Bytes that pass
the parity check have the MSB set to a logic 0 and are
written into page memory. Bytes with parity errors are not
written into the memory.
