1355PWR Software Suspend Power Sequencing Utility
Issue Date: 98/10/30
1355PWR
1355PWR is a diagnostic utility used to test some of the power save capabilities of the SED1355.
1355PWR enables or disables the software suspend mode, hardware suspend mode, and the LCD,
allowing testing of the power sequencing in each mode.
To measure the timing for power sequencing, GPIO pin 1 is used to trigger an oscilloscope at the
point the requested power sequencing function is activated/deactivated. For further information on
LCD Power Sequencing and Power Save Modes, refer to the SED1355 Programming Notes and
Examples, document number X23A-G-003-xx, and the SED1355 Functional Hardware Specifi-
cation, document number X23A-A-01-xx.
The 1355PWR software suspend power sequencing utility must be configured and/or compiled to
work with your hardware platform. The program 1355CFG.EXE can be used to configure
1355PWR. Consult the 1355CFG users guide, document number X23A-B-001-xx, for more
information on configuring SED1355 utilities.
This software is designed to work in both embedded and personal computer (PC) environments. For
the embedded environment, it is assumed that the system has a means of downloading software from
the PC to the target platform. Typically this is done by serial communications, where the PC uses a
terminal program to send control commands and information to the target processor. Alternatively,
the PC can program an EPROM, which is then placed in the target platform. Some target platforms
can also communicate with the PC via a parallel port connection, or an Ethernet connection.
1355PWR supports the following SED1355 evaluation platforms:
• PC system with an Intel 80x86 processor.
• M68332BCC (Business Card Computer) board, revision B, with a Motorola MC68332
• M68EC000IDP (Integrated Development Platform) board, revision 3.0, with a Motorola
• SH3-LCEVB board, revision B, with an Hitachi SH-3 HD6417780 processor.
PC platform: copy the file 1355PWR.EXE to a directory that is in the DOS path on your hard drive.
Embedded platform: download the program 1355PWR to the system.
