Note
SAD2 Attribute (FP 3-2) bits [1:0]
These bits control the attributes of the second screen block (SAD2). These bits also con-
trol the attributes of the fourth screen block (SAD4) when it is enabled by setting the Panel
Drive Select bit to dual panel mode (REG[00h] bit 3 = 1). In this mode, the attributes of
the second screen block (SAD2) and the fourth screen block (SAD4) share the same set-
tings and cannot be set independently.
SAD1 Attribute (FP 1-0) bits [1:0]
These bits control the attributes of the first screen block (SAD1) as follows.
Cursor Attribute (FC) bits [1:0]
These bits control the cursor and set the flash rate. The cursor flashes with a 70% duty
cycle (ON 70% of the time and OFF 30% of the time).
When the cursor is disabled, a write to memory automatically enables the cursor and
places the cursor at the next memory location. A read from memory does not enable the
cursor, however, it still places the cursor at the next memory location.
