DESCRIPTION

System Error

This pin is asserted with one PCI clock width within

two PCI clocks after an address parity error is

detected, and keeps in high impedance state when

idle. The interrupt function caused by this event is

gated by the bits in F04/FCS register.

W89C841F will assert SERRB and will set a high to

the Detect Parity Error bit F04/FCS[31] and the Signal

System Erro bit F04/FCS[30] if an address parity

error is detected and SERRB enable bit F04/FCS[8]

is previously set to 1.

The Bus Error Status bit C14/CISR[13] will be set to

high if both an address parity error is detected and

the parity error response bit F04/FCS[6] is set to high.

Interrupt A

INTAB is asserted when any one of unmasked

interrupt bits in C14/CISR is set. It keeps asserted

until all of the unmasked interrupt bits is cleared.
