The active low system error signal (SERRB) indicates
an address parity error. Address parity errors are
detected when the even parity calculations during the
address phase do not match the PAR signal. When
the FREEDM-8 detects a system error, SERRB is set
low for one PCICLK period.
SERRB is enabled by setting the SERREN bit in the
Control/Status register in the PCI Configuration
registers space. Regardless of the setting of
SERREN, parity errors are always reported by the
SERR bit in the Control/Status register in the PCI
Configuration registers space.
SERRB is an open drain output and is updated on the
rising edge of PCICLK.
