8 to 12, 14 to 16 & 19 to 22PIN1, 2, 5 to EI/O, please refer to Pin mux table 5. Pin muxIn addition to acting as a GPIO, each pin on the imp002 can be configured to one of several specialized functions. While pins may only have one function at a time, they may be reconfigured during run-time to change function as needed. For example, a pin may first be configured as a DAC and then reconfigured as an ADC. Additionally, not all the pins in a hardware function need to be assigned to that function. For example, pins 8 and 9 could be used as UART and pins 1 and 2 could be used as I2C.All I/O pins are initially tri-stated.The imp002 can be woken from low power sleep mode with a rising edge on PIN1. If this signal is pulsed, the minimum pulse width is 20ms.PinGPIOUARTI2CSPIDACADCPWMPulse CountWakePIN 1YesU1-CTS, U3-TXI1-SCLSPI1-SCLKYesYesYesYesYesPIN 2YesU1-RTS, U3-RXI1-SDASPI2-MISOYesYesPIN 5YesU2-TXSPI2-SCLKYesYesYeselectric imp, incelectric imp imp002 specification (confidential, not for distribution)"5
