6.14.2.13 GLCP System Reset and PLL Control (GLCP_SYS_RSTPLL)
MSR Address
Type
Reset Value
This register is initialized during POR, but otherwise is not itself reset by any “soft-reset” features. Note that writing this reg-
ister always has immediate effect, so read-modify-writes must be done to avoid corrupting the PLL timing settings. When
using this register functionally to change PLL frequencies, the CHIP_RESET bit (bit 0) should be set. Writing this register
with the CHIP_RESET bit set will never send a write-response over the GLIU (this allows halting bus traffic before the reset
occurs).

GLIU Multiplier (Bootstrap Dependent, see Table 6-87).
00000: Multiply by 1,....
11111: Multiply by 32.
GLIU Divide. When set, predivide the GLIU PLL input frequency by 2.
0: Do not predivide input. (Default)
1: Divide by 2.
CPU Core Multiplier (bootstrap dependent, see Table 6-87 on page 556).
00000: Multiply by 1,....
11111: Multiply by 32.
CPU Core Divide. When set, predivide the GLIU PLL input frequency by 2.
0: Do not predivide input. (Default)
1: Divide by 2.
Flags. Flags that are reset only by the POR# signal, not the CHIP_RESET (bit 0). They
are reset to 0 and can be used as flags in the boot code that survive CHIP_RESET.
Lock (Read Only). Lock signal from the system PLL. The worst-case lock time for a
AMD Geode™ LX processor PLL is 100 µs.
