Table 4-9 describes the registers of the clock generator and PLL.

Table 4-8. Clock Generator Configuration

Bit Description

Offset 10h Maximum Core Clock Multiplier Register - MCCM (RO) Reset Value: Strapped Value

This register holds the maximum core clock multiplier value. The maximum clock frequency allowed by the core, is the Fast-PCI clock

multiplied by this value.

7:4 Reserved.

3:0 MCM (Maximum Clock Multiplier). This 4-bit value is the maximum multiplier value allowed for the core clock generator. It

is derived from strap pins CLKSEL[3:0] based on the multiplier value in Table 4-7 on page 89.

Offset 11h Reserved - RSVD

Offset 12h PLL Power Control Register - PPCR (R/W) Reset Value: 2Fh

This register controls operation of the PLLs.

7Reserved.

6EXPCID (Disable External PCI Clock).

0: External PCI clock is enabled.

1: External PCI clock is disabled.

5GPD (Disable Graphic Pixel Reference Clock).

0: PLL2 input clock is enabled.

1: PLL2 input clock is disabled.

4Reserved.

3PLL3SD (Shut Down PLL3). AC97 codec clock.

0: PLL3 is enabled.

1: PLL3 is shutdown.

2FM1SD (Shut Down PLL4).

0: PLL4 is enabled.

1: PLL4 is shutdown, unless internal Fast-PCI clock is strapped to 48 MHz.

1C48MD (Disable SuperI/O and USB Clock).

0: USB and SuperI/O clock is enabled.

1: USB and SuperI/O clock is disabled.

0Reserved. Write as read.

Offset 13h-17h Reserved - RSVD

Offset 18h-1Bh PLL3 Configuration Register - PLL3C (R/W) Reset Value: E1040005h

31:24 MFFC (MFF Counter Value).

Fvco = OSCCLK * MFBC / (MFFC * MOC)

OSCCLK = 27 MHz

23:19 Reserved. Write as read.

18:8 MFBC (MFB Counter Value).

Fvco = OSCCLK * MFBC / (MFFC * MOC)

OSCCLK = 27 MHz

Note: Bits 18, 9, and 8 cannot be changed. Bit 18 is always a 1; bits 9 and 8 are always 0.

7Reserved. Write as read.

6Reserved. Must be set to 0.

5:0 MOC (MO Counter Value).

Fvco = OSCCLK * MFBC / (MFFC * MOC)

OSCCLK = 27 MHz

Offset 1Eh-1Fh Core Clock Frequency Control Register - CCFC (R/W) Reset Value: Strapped Value

This register controls the configuration of the core clock multiplier and the reference clocks.
