8/30 READING
8/30 packetis read at row 23 equivalent address.
R8 register must be programmed with D3, D2,
D0 = 0 and D2 = 1 (8/30selection).
R9 register mustbe programmedwith 23 (17h).
R10 register value corresponds to the position of
the byte to be read (from 0 to 39).
R11Acontents the value of the needed byte.

Table 2 :
Registerspecification
REGISTERMAP (see Table 2)
RegistersR0 to R10 are write onlywhilst R11Aisa
read/writeand R11Bis aread onlyregister respect
to the microprocessor.
The automatic succession on a byte basis is indi-
cated by the arrows in Table 2.
In the normal operating mode TA, TB and TC
should be set to logic level 0.
After power-up thecontents of the registers areas
follows: all bits in registers R0 to R11Aarecleared
to zero with the exception of bits D0 and D1 in
registersR5 and R6 whichare set to logical one.
After power-up all the memory bytes are preset to
hexadecimalvalue20H(space)withthe exception
of the byte corresponding to row 0 of column 7 of
chapter 0 which is set to the value corresponding
to ”alphawhite” hexadecimalvalue 07 H.
