This section describes the registers used to set SwivelView mode operation.
The start address registers must be set for SwivelView mode. In SwivelView mode the
offset contained in the start address points to a byte.
The line byte count register informs the SED1374 of the stride, in bytes, between two
consecutive lines of display in SwivelView mode. The Line Byte Count register only
affects SwivelView mode operation. The contents of this register are ignored when the
SED1374 is in landscape display mode.
The SwivelView mode register contains several items for SwivelView mode support.
The first is the SwivelView Mode Enable bit. When this bit is “0” the SED1374 is in
landscape mode and the remainder of the settings in this register as well as the Line Byte
Count in REG[1Ch] are ignored. When this bit is a “1” SwivelView mode is enabled.
There are two SwivelView mode display schemes available. The SwivelView mode select
bit selects between the “Default Mode” and the "Alternate Mode”. The default mode offers
the lowest power consumption with some display mode limitations. The alternate mode
uses more power but offers greater display flexibility.
