RGANIZATION
The display data is 1-bit per pixel and stored in a
dual port static RAM (RAM, for Display Data RAM).
The RAM size is 65 x 132 for UC1606. This array
of data bits is further organized into pages of 8 bit
slices to facilitate parallel bus interface.
When Mirror X (MX, LC[2]) is OFF, the 1
st
column
of LCD pixels will correspond to the bits of the first
byte of each page, the 2
column of LCD pixels
correspond to the bits of the second byte of each
page, etc.

There are two options to map D[7:0] to RAM, MSB
first (MSF=1), or LSB first (MSF=0), as illustrated in
next page.

CCESS
The memory used in UC1606 Display Data RAM
(RAM) is a special purpose dual port RAM which
allows asynchronous access to both its column and
row data. Thus, RAM can be independently
accessed both for Host Interface and for display
operations.

DDRESSING
A Host Interface (HI) memory access operation
starts with specifying Page Address (PA) and
Column Address (CA) by issuing
Set Page Address
and
Set Column Address
commands.
If wrap-around (WA, AC[0]) is OFF (0), CA will stop
increasing after reaching the end of page , and
system programmers need to set the values of PA
and CA explicitly.
