HBM1X1M bluetooth v1.2 class 1 module data book 3.2 usb this bluetooth module contains a full speed (12mbit/s) usb interface that is capable of driving a usb cable directly. no external usb transceiver is required. the device operates as a usb peripheral, responding to requests from a master host controller such as a pc. both the ohci and the uhci standards art supported. the set of usb endpoints implemented can behave as specified in the usb section of the bluetooth specification v1.2 or alternatively can appear as a set of endpoints appropriate to usb audio devices such as a set of usb speakers. since usb is a master/slave oriented system (in common with other usb peripherals), this module only supports usb slave operation. 3.3 spi (serial peripheral interface) bluecore3-multimedia external uses 16-bit data and 16-bit address serial peripheral interface, where transactions may occur when the internal processor is running or is stopped. the bluecore3-multimedia external is the slave and receives commands on spi_mosi and outputs data on spi_miso. 1 reset the spi interface hold spi_csb high for two spi_clk cycles 2 write the command word take spi_csb low and clock in the 8 bit command 3 write the address clock in the 16-bit address word 4 write or read data words clock in or out 16-bit data word(s) 5 termination take spi_csb high 3.4 kalimba dsp the kalimba dsp is an open platform kalimba dsp allowing signal processing functions to be performed on over-air data or codec data in order to enhance audio applications. www.hanamciron.co.kr 13 page / 17 pages
