When the size of data is less than 1024 bytes, the time GPIO37 takes to become low after step 5 is 16 clock cycles (WRITE_RESPONSE + Data Header). When the size of data is more than 1024 bytes, the time taken wait cycle will be (Data length-1024+16) clocks.
Page 46 GS2200M IP2WiFi Adapter Command Reference Guide 3. When GS node receives A first 4bytes of READ_REQUEST in SPI FIFO, it triggers an interrupt to pull the GPIO37 LOW. Here the MCU need not wait for GPIO37 to go HIGH. After receiving the READ_REQUEST, GS node parses the READ REQUEST, formulates the READ RESPONSE, puts the READ RESPONSE along with the Data header in the PING buffer, and pulls the GPIO37 high.
Page 47 GS2200M IP2WiFi Adapter Command Reference Guide 3.2.2.2.2 Polling Methodology This method can only be used if the MCU is not capable to generate the interrupts where the MCU is single threaded. Currently its not recommended to use this mode. For high speed MCUs, it is always recommended to use interrupt mode.
