28 / 87 page  STRAP OPTION 28/87 Release 1.3 - January 29, 2002 This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. 3.1. POWER ON STRAP REGISTER DESCRIPTIONS 3.1.1. STRAP REGISTER 0 CONFIGURATION Strap0 Access = 0022h/0023h Regoffset = 04Ah 76543210 MD7 MD6 MD5 MD4 MD3 MD2 Rsv This register defaults to the values sampled on MD[7:0] pins after reset Bit Number Sampled Mnemonic Description Bits 7-6 MD[7:6] PCICLK Programming; the PCICLK PLL is setup through MD[7:6]. The PLL setup will vary depending on the PCICLK frequency. See Table 3-2 for details. Bit 5 MD5 This bit reflects the value sampled on MD[5] pin and controls the MCLK/ HCLK Synchronization. When MCLK and HCLK frequency are the same, when set to 1 it unifies HCLK and MCLK and so improves system performance. Bit 4 MD4 This bit reflects the value sampled on MD[4] pin and controls the PCICLKO division. It works in conjunction with MD[17]; refer to Section 3.1.3. bit 1 for more details. Bits 3-2 MD[3:2] See Section 3.1.4. Bits 1-0 Rsv Reserved. Table 3-2. PCI Clock Programming Bit 7 Bit 6 Description 0 0 PCICLK frequency between 16 & 32 MHz 0 1 PCICLK frequency between 32 & 64 MHz 1 X Reserved |
