System
• Portrait Mode - selecting Portrait Mode causes register settings and timings to be saved
for portrait mode operation.
The HAL is capable of performing rotations “on the fly”. Most programs written for the
HAL will ignore this setting and set Portrait or Landscape display modes as desired.
This setting is useful when the configuration is saved into a C header file to be used by
non-HAL programs.
The options in the System section describe the items which are required for frame rate
calculations and where in CPU address space the SED1374 will be located.

• Memory Location - this describes where in CPU address space the SED1374 will be
located. This setting is required by the HAL to locate the SED1374. If the settings from
1374CFG will be saved to a C header file for use in a non-HAL program this value does
not have to be filled in.
• Frame Rate - indicate the desired frame rate here. 1374CFG will attempt to write
register settings which result in the requested frame rate. If the frame rate cannot be
reached then the following dialog inform the user of the problem
