Preliminary
17.18: PCORE High Priority Access Timer Value Registers
These registers are used to load timers that count to zero from the value loaded in this register. The
maximum wait for an I/O transaction is about 2ms when this is set to X’FFFF’. The value of this register is
written into the corresponding timer after the transaction is initiated with the target. It will continue to then
count down until the target responds or zero is reached in the timer. When the timer reaches zero, a status bit
is set and action can be taken from there.

17.19: PCORE Transaction Dead Man Timer Register
These timers are used to time transactions that are valid but the target does not respond right away. The
timer counts on a 7.5 ns time base. The maximum wait for an I/O transaction is about 2ms when the timer
counts down from X’FFFF’. This timer counts down to zero from the values set in the value register. When
zero is reached, the transaction is considered broken and the request will be acknowledged back to the
requestor.
