Hardware Description Manual
3.5.8 Synchronous Serial Interface
3.5.9 UART
This is a standard UART interface for communicating with other serial devices.
3.6 Microcontroller
The MCU, interrupt controller and event timer run the Bluetooth software stack and control the radio and host
interfaces. A 16-bit RISC microcontroller is used for low power consumption and efficient use of memory.
3.6.1 Programmable I/O
BlueCore 5 chip has a total of 18 programmable I/O terminals (16 digital and 2 analog). These are controlled by
firmware running on the device.
3.6.2 802.11 Coexistence Interface
Dedicated hardware is provided to implement a variety of 802.11 (Wi-Fi) coexistence schemes. Channel skipping
AFH, priority signalling, channel signalling and host passing of channel instructions are all supported. The features
are configured in firmware. The details of some methods are proprietary. Contact CSR for details.
