System Power Up/Down and Reset Settings Hardware Reset Note 6.2.1 Reset (SYSRSTn signal) must be active for a minimum length of 5 ms. core power, I/O power, and analog power must be stable (VDD +/- 5%) during that time and onward. Reset Out Signal The device has an optional SYSRST_OUTn output signal, multiplexed on an MPP pin, that is used as a reset request from the device to the board reset logic. SYSRST_OUTn is the default option for that MPP pin.
88F6281 Hardware Specifications 6.3 PCI Express Reset 6.3.1 PCI Express Root Complex Reset As a Root Complex, the device may generate a Hot Reset to the PCI Express port. Upon CPU setting the PCI Express Control register’s bit, the PCI Express unit sends a Hot Reset indication to the Endpoint, see the PCI Express Interface section in the 88F6180, 88F6190, 88F6192, and 88F6281 Functional Specifications. 6.3.
System Power Up/Down and Reset Settings Pins Sample Configuration Note If external logic is used instead of pull-up and pull-down resistors, the logic must drive all of these signals to the desired values during SYSRSTn assertion. To prevent bus contention on these pins, the external logic must float the bus no later than the third TCLK cycle after SYSRSTn de-assertion.

88F6281 Hardware Specifications 7.3 Bypass Register The Bypass register (BR) is a single bit serial shift register that connects TDI to TDO, when the IR holds the Bypass command, and the TAP FSM is in Shift-DR state. Data that is driven on the TDI input pin is shifted out one cycle later on the TDO output pin. The Bypass register is loaded with 0 when the TAP FSM is in the Capture-DR state. 7.
