? 15 ? CXN1010 external interfaces uart interface the uart interface makes it easy to communicate with other serial devices using the rs-232 standard ? 1 . CXN1010 uart_tx uart_rx uart_rts uart_cts 29 30 28 36 uart pins as shown in the figure above, four signals are used to execute the uart function. when the CXN1010 is connected to another digital device, data is transmitted between the two devices using the uart_rx and uart_tx signals. the remaining two low active signals, uart_cts and uart_rts, can be used for rs-232 hardware flow control. all the uart pins are configured as cmos i/o pins. their signal levels are 0v and v dd 3.0. the baud rate, packet format and other uart configuration parameters are set using ps tool or other bluecore software. note: in order to communicate with uart at the maximum data rate using a standard pc, a serial port adapter card with acceleration must be installed in the pc. ? 1 the rs-232 protocol is used, but the voltage level is from 0v to v dd 3.0. (an rs-232 transceiver ic must be externally attached.) uart settings parameter baud rate flow control parity number of stop bits bits per channel possible values 1200 baud ( 2% error) 9600 baud ( 1% error) 1.5m baud ( 1% error) rts/cts or none none, odd or even 1 or 2 8 minimum maximum
? 16 ? CXN1010 break signal with the uart interface, the CXN1010 can be reset as soon as a break signal is received. as shown in the figure below, the break is identified by the continuous low logic level in the uart_rx pin. resetting occurs if t brk is longer than the value defined by pskey_host_io_uart_reset_timeout (0x1a4) persistent store key. the system can be initialized to a known status from the host using this function. the CXN1010 can also send break characters that can be used for starting the host. the frequently used baud rates and the values of the pskey_uart_baud_rate (0x204) persistent store key linked to those rates are shown in the table below. these standard values are not necessarily required conditions, and all baud rates within the range supported can be set by the persistent store key with the following equation. baud rate = uart_rx t brk standard baud rates pskey_uart_baud_rate 0.004096 baud rate 1200 2400 4800 9600 19200 38400 57600 76800 115200 230400 460800 921600 1382400 error 1.73% 1.73% 1.73% ?0.82% 0.45% ?0.18% 0.03% 0.14% 0.03% 0.03% ?0.02% 0.00% ?0.01% hex 0x0005 0x000a 0x0014 0x0027 0x004f 0x009d 0x00ec 0x013b 0x01d8 0x03b0 0x075f 0x0ebf 0x161e dec 5 10 20 39 79 157 236 315 472 944 1887 3775 5662 persistent store value
? 17 ? CXN1010 usb interface the usb pins of the CXN1010 support a full speed (12mbps) usb interface. they enable direct drive of the usb cable, thereby obviating the need for an external usb transceiver. with this interface, the CXN1010 can operate as a usb unit and respond to requests from a pc or other master host controller. the interface supports both ohci and uhci standards. it also complies with bluetooth specifications ver.1.1 and part h2. although usb is a system that is capable of both master and slave operations, the CXN1010 supports usb slave operations only. serial peripheral interface (spi) when data is sent or received through the spi pins, the CXN1010 uses 16-bit data and 16-bit addresses. through these pins, data is transmitted and received while the internal processor is operating and not operating. data is written or read one word at a time unless the auto increment function is used to access blocks. spi_clk spi_mosi spi_miso write command address spi_csb spi_clk spi_mosi spi_miso don't care xs xs c0 a15 a14 a0 c7 c6 t15 t14 d0 data don't care write operation b write operation a

CXN1010 pcm interface master/slave when the CXN1010 is set as the pcm interface master, pcm_clk and pcm_sync are generated. pcm interface master when the CXN1010 is configured as the pcm interface slave, pcm_clk rates up to 2048khz are accepted. pcm interface slave 128/256/512khz 8khz CXN1010 pcm_out pcm_in pcm_clk pcm_sync 34 31 35 32 pcm_out pcm_in pcm_clk pcm_sync up to 2048khz 8khz CXN1010 34 31 35 32
? 20 ? CXN1010 pio port the parallel input/output (pio) port serves as the general-purpose i/o interface of the CXN1010. it consists of nine programmable bidirectional i/o lines. these programmable i/o lines can be accessed via either the installed application run by the CXN1010 or the private channel or manufacturer-designated hci commands. pio[0]/rxen this multi-functional terminal is a programmable i/o line. either the programmable i/o or control output for external lna (if fitted). pio[1]/txen this multi-functional terminal is a programmable i/o line. either the programmable i/o or control output for external pa class1 applications only. pio[2]/usb_pull_up ? 1 this multi-functional terminal is a programmable i/o line. either the programmable i/o or pio or usb pull-up (via 1.5k ? resistor to usb_d+). pio[3]/usb_wake_up ? 1 this multi-functional terminal is a programmable i/o line. either the programmable i/o or usb_wake_up function can be selected with the pskey_usb_pio_wakeup (0x2cf) persistent store key setting. pio[4]/usb_on ? 1 this multi-functional terminal is a programmable i/o line. it can also be used as the usb_on function. pio[5]/usb_detach ? 1 this multi-functional terminal is a programmable i/o line. it can also be used as the usb_detach function. pio[6]/clk_req this is a multi-functional terminal whose function is determined by the persistent store keys. using pskey_clock_request_enable (0x246), it can be set to low when the CXN1010 is in deep sleep and to high when a clock is requested. if a shift in the timing in certain operation modes is to be avoided, the clock must be supplied within 4ms from the pio[6] rising edge. pio[7] programmable i/o terminal pio[8] programmable i/o terminal
