NOTES:
1. Maximum I_ol for CPUPWRGD is 12 mA for short durations (<500 mS per 1.5 s) and 9 mA for long durations.
2. The SERR#, PIRQ[H:A], GPIO11, SMBDATA, SMBCLK, LINKALERT#, and SMLINK[1:0] signal has an open drain
driver and SATALED# has an open collector driver, and the V_OH spec does not apply. This signal must have an
external pull-up resistor.
3. PCI Express mVdiff p-p = |PETp[x] – PETn[x]|
