General Configuration Block
4.5.2
The core clock is generated by an Analog Delay Loop
(ADL) clock generator from the internal Fast-PCI clock. The
clock can be any whole-number multiple of the input clock
between 4 and 10. Possible values are listed in Table 4-6.
At power-on reset, the core clock multiplier value is set
according to the value of four strapped balls - CLKSEL[3:0]
(balls P30, D29, AF3, B8). These balls also select the clock
which is used as input to the multiplier, as shown in Table
4-7.
4.5.3
The internal Fast-PCI clock can be configured to 33, 48, or
66 MHz via strap options on the CLKSEL1 and CLKSEL0
balls. These can be read in the internal Fast-PCI Clock field
in the CCFC register (GCB+I/O Offset 1Eh[9:8]). (See
Table 4-9 on page 92 details on the CCFC register.)
Note: Not all speeds are supported. For information on supported speeds, see Section A.1 "Order Information" on page
