... UART_RX terminal, as shown in Figure 7. If tBRK is longer than the value, defined by PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur. This feature allows a host to initialise the system to a known state. Also, WT11i can emit a break character that may be used to wake the host. ...

... UART Bypass 6.2 UART Configuration While Reset is Active The UART interface for WT11i while the chip is being held in reset is tristate. This will allow the user to daisy chain devices onto the physical UART bus. The constraint on this method is that any devices connected to this bus must tristate when WT11i reset is de-asserted and the firmware begins to run. ...

... USB hub or root port. However, it requires that VBUS be connected to WT11i via a resistor network (Rvb1 and Rvb2), so WT11i can detect when VBUS is powered up. BlueCore4-External will not pull USB_DP high when VBUS is off ...
Page 19
... For WT11i, the USB power descriptor should be altered to reflect the amount of power required. This is accomplished by setting PSKEY_USB_MAX_POWER (0x2c6). This is higher than for a Class 2 application due to the extra current drawn by the Transmit RF PA. By default for WT11i the setting is 300 mA. When selecting a regulator, be aware that VBUS may go as low as 4.4V. The inrush current (when charging reservoir and supply decoupling capacitors) is limited by the USB specification ...

... USB_WAKE_UP. These are outside the USB specification (no wires exist for them inside the USB cable), but can be useful when embedding WT11i into a circuit where no external USB is visible to the user. Both control lines are shared with PIO pins and can be assigned to any PIO pin by setting PSKEY_USB_PIO_DETACH and PSKEY_USB_PIO_WAKEUP to the selected PIO number ...

... Bluetooth software running on the host computer. Please, contact 7.9 USB v2.0 Compliance and Compatibility Although WT11i meets the USB specification, CSR cannot guarantee that an application circuit designed around the module is USB compliant. The choice of application circuit, component choice and PCB layout all affect USB signal quality and electrical characteristics. The information in this document is intended as a guide and should be read in association with the USB specification, with particular attention being given to Chapter 7 ...

... The SPI port can be used for system debugging. It can also be used for programming the Flash memory and setting the PSKEY configurations. WT11i uses 16-bit data and 16-bit address serial peripheral interface, where transactions may occur when the internal processor is running or is stopped. SPI interface is connected using the MOSI, MISO, CSB and CLK pins ...

... PCM_CLK to half the PCM_SYNC rate, i.e., 62.5s long. Figure 15: Long Frame Sync (Shown with 8-bit Companded Sample) WT11i samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge ...

... The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8kHz. With WT11i in Slave mode, the frequency of PCM_CLK can 4.096MHz. 9.6 Slots and Sample Formats WT11i can receive and transmit on any selection of the first four slots following each sync pulse. Slot durations can be either clock cycles ...

... Figure 19: 16-bit Slot Length and Sample Formats 9.7 Additional Features WT11i has a mute facility that forces PCM_OUT master mode, PCM_SYNC may also be forced to 0 while keeping PCM_CLK running which some codecs use to control power down. 9.8 PCM_CLK and PCM_SYNC Generation WT11i has two methods of generating PCM_CLK and PCM_SYNC in master mode. The first is generating these signals by DDS from BlueCore4-External internal 4MHz clock ...

... Reset WT11i may be reset from several sources: RESET pin, power on reset, a UART break character or via software configured watchdog timer. The RESET pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB being active ...
