HelloApp
This section covers the HAL functions dealing with the Power Save features of the SED1355.
int seSWSuspend(int DevID, BOOL Suspend)
Description:
Parameters:
Return Value: ERR_OK
int seHWSuspend(int DevID, BOOL Suspend)
Description:
Parameters:
Return Value: ERR_OK
Building Epson applications like a simple HelloApp for a new target platform requires 3 things, the
HelloApp code, the 1355HAL library, and a some standard C functions (portable ones are encapsu-
lated in our mini C library LIBSE).

Causes the SED1355 to enter software suspend mode.
When software suspend mode is engaged the display is disabled and display buffer
is inaccessible. In this mode the registers and the LUT are accessible.
DevID
Suspend
Causes the SED1355 to enter/leave hardware suspend mode. This option in only
supported on SED1355B0B ISA evaluation boards.
When hardware suspend mode is engaged the display is disabled and display buffer
is inaccessible and the registers and LUT are inaccessible.
