Preliminary
2.12: INTST CPB Captured Address
This information can be used to attempt a retry in the exception handling microcode. This register holds the
value of the IBM3206K0424 register address on the PCI during a bus error condition. This only latches values
from sources that are enabled in the INTST CPB Capture Enable register.

2.13: INTST General Purpose Timer Pre-scaler
This is the pre-scaler for the INTST General Purpose Timer Compare.This register will hold the value of the
pre-scale count. The default value is 1 tick every 10.02uS, assuming a 33MHz or 66MHz PCI Bus clock, pro-
ducing a 66MHz system clock (count is system clock). The pre-scale count value is n-1, where n is the
desired increment count.
Owing to a physical design problem, the function of this register was lost. It should be set to a non-zero value,
so that the INTST General Purpose Timer Counter can be used with a prescale of only the default clock (one
tick every 30ns, assuming a 33-MHz system clock).
