WebSep 24, 2016 · The HOLD/RST bit is used to determine whether /HOLD or /RESET function should be implemented on the hardware pin for 8-pin packages. When HOLD/RST=0 (factory default), the pin acts as /HOLD; when HOLD/RST=1, the pin acts as /RESET. However, /HOLD or /RESET functions are only available when QE=0. WebConfigure it for your capture. Set D0 to MOSI. Set D1 to MISO. Set D2 to IO2 (WP on 8 pin flashes usually.) Set D3 to IO3 (HOLD on 8 pin flashes usually.) Set D15 to CS (used to ignore extra clocks.)
