26.3.19 System PLL Configuration Register (SCG_SPLLCFG)
The SPLLCFG register cannot be changed when the System PLL is enabled. When the
System PLL is enabled, writes to this register are ignored, and there is no transfer error.
The below information applies to VCO_CLK.
The SPLL_CLK = (VCO_CLK)/2
The VCO_CLK = SPLL_SOURCE/( 1) X (MULT + 16)
SPLL_SOURCE is the clock source selected from the SOURCE bitfield of this register.
Address: 4006_4000h base + 608h offset = 4006_4608h
