CPU power management
3. In the same .PMI file, select any signal that will cause the system to
resume. The options include IRQs, COM2 RI, and External PMI signal
(EPMI), J10. Refer to the IRQ routing and opto IRQs chapter for the
EPMI connection and signal requirements.
The input used depends upon the ISP setup. The following are the
default signals at J10:
J10[1-2] OPTOA
PMI
J10[3-4] OPTOB
SUSPEND/RESUME
TEST.PMI file:
irq1-resume-reset=Y
Enables RESUME if IRQ1 occurs
(keyboard input)
irq4-resume-reset=Y
Enables RESUME if IRQ4 occurs
(COM1 input)
RI-resume-reset=Y
Enables RESUME if RI occurs
(COM2 ring indicator)
RI-transitions=5
Specifies number of RI transitions
(n) for RESUME (COM2
ring indicator)
EPMI-resume-reset=Y
Enables RESUME if EPMI occurs
(external PMI signal)
4. Load the .PMI file changes by including the .PMI file on the PMISETUP
command line. PMISETUP is located in the \UTILS directory:
PC500 C:\> PMISETUP TEST.PMI
5. Hardware reset the system for the PMISETUP options to take effect.
The PC-500 system is now ready for SUSPEND/RESUME.
6. Initiate a SUSPEND/RESUME input signal at J10[3-4] or allow the
“suspend-delay” timer to expire. Refer to the IRQ routing and opto
IRQs chapter for the EPMI connection and signal requirements.
7. The PC-500 system enters the SUSPEND mode, powering down any
devices that can be powered down.
8. A system RESUME is generated by any event defined in the .PMI file or
the when an external RESUME signal is applied at J10[3-4]. If a VGA
monitor is attached, the video will return. If a hard drive is attached,
the drive will not spin up until accessed.
Note
The default signals at J10 are [1-2] PMI and [3-4] SUSPEND/RESUME.
These signals may be changed by reprogramming the IRQ matrix. See
the IRQ routing and OPTO IRQs chapter for more information on the
IRQ matrix.
WAKEIRQ8.EXE is a sample TSR that wakes the CPU, using the
CMOS clock, from SUSPEND mode after a 30 second delay.
WAKEIRQ8.EXE and WAKEIRQ8 files are available in the
\EXAMPLES directory on the PC-500 utility disk.
