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.
