(seeTable 3)
Registers R0 to R10 are write only whilst R11Ais
a read/writeand R11B is read only.
The automaticsuccessionon a byte by byte basis
is indicatedby the arrows in Table3.
In the normaloperatingmode TB shouldbe set to
logic level 0.
Table2 :
PDCData Storage in Chapter 5
After power-up the contents of the registersare as
follows: all bitsin registersR0 to R11Aare cleared
to zero with the exception of bits D0 and D1 in
registersR5 and R6 which are set to logicalone.
After power-up all the memory bytes are presetto
hexadecimalvalue20H(space)with the exception
of the byte correspondingto row 0 of column 7 of
chapter 0 which is set to the value corresponding
to “alpha white” hexadecimalvalue 07H.
In 4 pages mode, R1D4 (ghost row enable) is set
to ’0’. In this mode, the X/24, X/26, X/27, X/28
packets of the selected pages,and the 8/30pack-
ets, are not stored.
In 2 pages mode, R1D4 (ghost row enable) is set
’1’. In this mode two displayable pages can be
storedin chapter0and1, andtheghostrowsofthe
selected pages, and the 8/30 packets, are stored
in chapter4 and 5.
