22.4 Pins
The interface has two device pins to connect to the off-chip user provided antenna. The ANT device pin is the radio
frequency signal pin and it should be routed through the ANT THRU device pin to the antenna. The ANT device pin is a 50Ω
source impedance driver.
22.5 Configuration
The Radio and Hardware Accelerator requires a 32MHz external crystal specified in the datasheet. The CPU core hosting the
Arm Cordio-B50 stack must run at a core speed greater than 32MHz.
Perform the following steps to enable the Bluetooth radio:
1. Set GCR_BTLE_LDOCR.ldorxen and set to GCR_BTLE_LDOCR.ldotxen 1 to enable the internal Bluetooth LDO.
2. Set GCR_CLK_CTRL.x32M_en to 1.
