14 P0.29 I/O ADC IN 15 P0.30 I/O ADC IN Note 1: P0.20 and P0.24 are reserved for PA control internal. Note 2: An internal 4.7μF bulk capacitor has been included on the module. it is good design practice to add additional bulk capacitance(e.g 10uF) as required for your application. General Purpose I/O: The general purpose I/O is organized as one port enabling access and control of the 32 available GPIO pins through one port. Each GPIO can be accessed individually with the following user configurable features:  Input/output direction  Output drive strength  Internal pull-up and pull-down resistors  Wake-up from high or low level triggers on all pins  Trigger interrupt on all pins  All pins can be used by the PPI task/event system; the maximum number of pins that can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels  All pins can be individually configured to carry serial interface or quadrature demodulator signals PA control: Additional logic signals are needed to control TX PA and RX LNA. On the nRF51 there was an option to use the VDD_PA pin to detect when the radio was in TX mode, but this is not an option on the nRF52, making the SoftDevice solution necessary. The S132 SoftDevice for the nRF52 has support for enable/disable switching of external Power Amplifiers (PA) and LNA using GPIO pins. On the module, P0.20 and P0.24 are reserved to control PA and LNA, so these two pins can Not be allocated to other usage. The truth table of PA/LNA control signals as bellow: PIN24 PIN20 PA status 1 0 TXEN 0 1 RXEN 0 0 IDLE 1 1 INVALID The following function can be used to enable PA/LNA signal with P0.20 and P0.24. Add this function to your project and call it after ble_stack_init(): static void pa_assist(uint32_t gpio_pa_pin,uint32_t gpio_lna_pin) { ret_code_t err_code; COPYRIGHT ©2016 ALL RIGHTS RESERVED XunTong Tech TEL: +86 755 26675941 E-mail: nrf@freqchina.com 4

Hardware RESET: There is on-chip power-on reset circuitry, But can still be used in external reset mode, in this case, GPIO pin P0.21 as an external hardware reset pin(Active Low). In order to utilize P0.21 as a hardware reset, the UICR registers PSELRESET[0] and PSELRESET[1] must be set alike, to the value of 0x7FFFFF15. When P0.21 is programmed as RESET, the internal pull-up is automatically enabled. HW debug and flash programming of Module: The Module support the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful mechanism for non-intrusive debugging of program code. Breakpoints, single stepping, and instruction trace capture of code execution flow are part of this support.
