PC-500 major software features
Advanced power management and system management
input
Power management can be used to reduce power consumption or to
freeze the state of the program on the occurrence of a power manage-
ment interrupt. Power consumption can be reduced by more than 60%.
This reduces the heat load and extends the battery life in mobile appli-
cations. There are opto-isolated system management and suspend/
resume inputs with 4-6V ranges. A system management input (SMI)
will cause the PC-500 to save its current status. When the system is
signaled to restart, execution resumes at the point the system last
stopped. The following are functions in the advanced power manage-
ment and SMI:
n
Suspend/resume by SMI input and software — halts CPU
n
Wake up through various interrupts including keyboard, SMI
and serial port
n
Slow CPU by dividing clock
n
Contextual save to disk.
Diagnostic software verifies system integrity automatically
The PC-500 has built-in diagnostic software that can be used to verify
on-card I/O and memory functions. On powerup, a series of tests is
performed. If a problem occurs, the failed test can be identified by the
color sequence on an on-board, bicolored LED. The test is performed
automatically every time the system is reset or powered up. Software,
test equipment, monitor, keyboard, disks, or test fixtures are not re-
quired for memory verification. See the LED signaling “beep” codes
chapter for a complete listing of tests and failures and their descriptions.
SETUP information stored in EEPROM for high reliability
Loss of SETUP data is serious in industrial applications. Most PCs
store SETUP information in battery-backed CMOS RAM. If the battery
fails or is replaced during routine maintenance, this information is lost.
Without a keyboard and monitor in embedded applications, time con-
suming re-initialization is required. The PC-500 stores the SETUP
information in EEPROM with 1,536 bytes available to the user. Soft-
ware routines to use this available memory come with the PC-500.
