Notes:
1. The external bus clock (pci_clk) will be 1/2 the frequency of the internal bus clock (ipb_clk) at powerup. Therefore, 4 IPbus wait states
will translate to as little as 1 external wait state (i.e. peripheral must respond within 2 external clocks). The "slow" setting represents
48 IPbus clocks of wait, or 23 external clocks of wait External waits are "minus-1" because Chip Select may assert on falling edge
of external bus clock (dependant on internal timing).
2. For muxed boot ROM types, the width of ALE_b & TS_b will be 2 IPbus clocks (i.e. 1 external clock). This represents the "wide ALE"
setting in the LocalPlus Controller (LPC). Care must be taken if these clock relationships are to be changed during the boot
process. For the 1-to-1 internal-to-external clock setting (which must be programmed by software into the CDM), be sure to change
the ALE width setting (in LPC) *after* adjusting the clock relationship. Any fetches to the boot device between these two settings will
result in ALE and TS being 2 external clocks wide.
3. Only one boot mode can be enabled at a time. Large Flash and Most Graphics cannot be enabled at the same time. If neither Large
Flash or Most Graphics is enabled, boot will occur from the normal LocalPlus mode, either muxed or nonmuxed (depending on the
"boot_rom_type" configuration input).
