CND power supply
2 GPIO0 internal module, launch control foot
3 GPI01 internal access module to accept control foot
4 GPIO2 directly connected to the chip GIIO2 pin
5 VCC positive supply 3.3V
6 SDO 0-VDD V digital output provides a serial readback function of the internal control register
7 SDI serial data input. 0-VDD V digital input, this pin for 4-wire serial data clock function
8 SCLK serial clock input. 0-VDDV last month set of inputs. This pin provides a 4-wire serial data clock function
9 NSEL serial interface select input pin,0-VDDV digital input. This pin to 4-wire serial data bus select / enable function, this signal is also used, said the burst read / write mode.
10 NIRQ interrupt output pin
11 SDN Close the input pin. Input 0-VDDV digital. SDN = 0 in shutdown mode, so mode
