Access = 0022h/0023h
Description
PCICLK Programming; the PCICLK PLL is setup through
MD[7:6]. The PLL setup will vary depending on the PCICLK
frequency. See
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.
This bit reflects the value sampled on MD[4] pin and controls the
PCICLKO division. It works in conjunction with MD[17]; refer to
3.1.3.
