sii 3114 pci to serial ata controller data sheet silicon image, inc. ? 2007 silicon image, inc. 15 sii -ds-0103-d pci stop pin name: pci_stop_n pin number: 134 pci_stop_n indicates the current target is requesti ng that the master stop the current transaction. pci parity error pin name: pci_perr_n pin number: 131 pci_perr_n indicates a data parity error between the curr ent master and target on pci. on a write transaction, the target always signals data parity errors back to the master on pci_perr_n. on a read transaction, the master asserts pci_perr_n to indicate to the system that an error was detected. pci system error pin name: pci_serr_n pin number: 137 system error is for reporting address parity errors, data parity errors on special cycle command, or any other system error where the result will be catastrophic. t he pci_serr_n is a pure open drain and is actively driven for a single pci clock by the agent reporting the error. t he assertion of pci_serr_n is synchronous to the clock and meets the setup and hold times of all bused signals. however, the restoring of pci_serr_n to the deasserted state is accomplished by a weak pull-up. note that if an agent does not want a non-maskable interrupt (nmi) to be generated, a different r eporting mechanism is required. pci parity pin name: pci_par pin number: 140 pci_par is even parity across pci_ad[31:0] and pci_c be[3:0]_n. parity generation is required by all pci agents. pci_par is stable and valid one clock after the address phase. for data phases pci_par is stable and valid one clock after either pci_irdy_n is asserted on a write transaction or pci_trdy_n is asserted on a read transaction. once pci_par is valid, it remains valid until one clock after the completion of the current data phase. (pci_par has the same timing as pc i_ad[31:0] but delayed by one clock.) pci request pin name: pci_req_n pin number: 103 this signal indicates to the arbiter that this agent desires use of the pci bus. pci grant pin name: pci_gnt_n pin number: 98 this signal indicates to the agent that access to the pc i bus has been granted. in res ponse to a pci request, this is a point-to-point signal. every master has its own pci_gnt_n, which must be ignored while pci_rst_n is asserted. pci interrupt a pin name: pci_inta_n pin number: 95 interrupt a is used to request an interrupt on the pc i bus. pci_inta_n is open collector and is an open drain output. pci clock signal pin names: pci_clk pin number: 97 clock signal provides timing for all transactions on pci and is an input to every pci device. all other pci signals (except pci_rst_n, and pci_inta_n) are sampled on the rising edge of pci_clk. all other timing parameters are defined with respect to this edge.
