FUNCTIONAL DESCRIPTION (continued)
Figure 2
As described in the ”message format” paragraph,
an address consists of three fields : STRU[7:6],
BUF[11:8], DEPL[4:0].
The STRU[7:6] field indicates whether it is a PAGE
address or a ROW ATTRIBUTE / REGISTER ad-
dress. It also determines the address incrementa-
tion scheme.

It is a PAGE address. BUF provides the row
number (from 0 to 10) and DEPL provides the
character number (from 0 to 27). DEPL is incre-
: ROW 0 : STRU[7:6] = 0 or 1 - BUF[11:8] = 0 - DEPL[4:0] from 0 to 27
: STRU[7:6] = 11 - BUF[11:8] = 0

mented after each data message. When the write
of a row is completed, the write pointer is auto-
matically set to the next row first character.
It is also a PAGE address but the incrementation
scheme is a bit different : when the write of a row
is completed, the write pointer is automatically
set to the first character of the same row.
It is a row attribute or a register address.The BUF
field must be set to 0000 and the DEPL field is
incremented after each data access.
