When S_RESET_L is asserted by means of the secondary reset bit, PI7C8152x remains
accessible during secondary interface reset and continues to respond to accesses to its
configuration space from the primary interface.
CHIP RESET
The chip reset bit in the diagnostic control register can be used to reset the PI7C8152x and
the secondary bus.
When the chip reset bit is set, all registers and chip state are reset and all signals are
tristated. S_RESET_L is asserted and the secondary reset bit is automatically set.
S_RESET_L remains asserted until a configuration write operation clears the secondary
reset bit. Within 20 PCI clock cycles after completion of the configuration write operation,
PI7C8152x’s reset bit automatically clears and PI7C8152x is ready for configuration.
During reset, PI7C8152x is inaccessible.
CONFIGURATION REGISTERS
PCI configuration defines a 64-byte DWORD to define various attributes of PI7C8152x as
shown below.
