Table 6-87. Bootstrap Bit Settings And Reset State Of Glcp_Sys_Rstpll (Pw1 And Irq13 = 0) - AMD Geode LX 600@0.7W Data Book

33234H
The PW1 pin (66 MHz PCI) is wired directly to the COREDIV and GLDIV signals during reset. The IRQ13 pin (stall after
reset) has no effect on the PLL controls but is still stored in the BOOTSTRAP bits (MSR 4C000018h[7:1]). Table 6-87
shows examples of reset values when PW1 and/or IRQ13 are high during reset. The hard reset state of this register always
leaves the PLL in bypass mode. The BIOS must clear the bypass bits in order to achieve the desired frequency.
