?20 CXD2721Q-1 5. microcomputer interface [relevant pins] rvdt, trdt, sck, xlat, redy the CXD2721Q-1 performs the serial audio interface format setting and coefficient settings such as volume and microphone echo delay amount by serial data from the microcomputer. further, bidirectional communication such as internal data read from the CXD2721Q-1 to the microcomputer can be performed at the rate of once per 1 lrck. (1) pin configuration the five external pins indicated in the table below are assigned to the microcomputer interface. the microcomputer interface begins operation when xlat is received, so multiple CXD2721Q-1 can be used by connecting rvdt, trdt, sck and redy in common and controlling (wiring) only xlat separately. symbol rvdt trdt sck xlat redy i o i i o serial data input from microcomputer. serial data output to the microcomputer. high impedance status unless this pin is set to internal data read status by the microcomputer. therefore, pull-up or pull-down should be performed so that the potential is not unstable when this pin is not active. shift clock for serial data. input data from rvdt is taken according to the sck rise, and output data from trdt is sent out according to the sck fall. interprets the 8 bits of rvdt before this signal rises as transfer mode data, and the bits before that as address data. transfer prohibited when low level. transfer enabled when high. this pin is an open drain, and must be pulled up externally. i/o function table 5-1. microcomputer interface external pins
?21 CXD2721Q-1 (2) description of communication formats the data transfer timing between the microcomputer interface and the coefficient ram and setup register is called the sv cycle, and is generated once per 1 lrck. the sv cycle is generated immediately preceding the signal processing program, so it has absolutely no effect on signal processing, and there is no risk of the sound being cut. in read/write modes, address section + mode section + data section act as one package of data to perform data transfer between the microcomputer and the CXD2721Q-1.

?23 CXD2721Q-1 (4) details of communication methods the definitions of signal timing required for control from the microcomputer are given below. (4)-1. write first, address and mode section data are sent from the microcomputer, synchronized with sck, to the rvdt pin. the address section data is 8 bits for both the coefficient ram and setup register. the setup register has a 1- word length, so optional data can be transferred. address section data is transferred with lsb first. mode section data is fixed at 8 bits regardless of the transfer contents. the phase relationship between sck and rv data (data applied to the rvdt pin) has the following restrictions: rv data must be established before sck rises ( t ds 3 20ns). rv data must be held for 1 t + 20ns or more after sck rises ( t dh ). sck itself has the following restrictions: sck low level must be 1 t + 20ns or more ( t swl ). sck high level must also be 1 t + 20ns or more ( t swh ). after sck rises, which corresponds to the final mode section data, xlat rises ( t slp 3 20ns). the xlat low level width must be maintained at 1 t + 20ns or more ( t lwl ). further, fall timing restrictions are: for the preceding transfer, if redy falls due to sck, as for write, 3 t + 20ns or more is required ( t sld ). for the preceding transfer, if redy falls due to xlat, as for read, 20ns or more is required ( t ldr ). further, if preceding transfers have been performed and redy = low, xlat must wait for redy = high before rising. the procedure until this point is the same for write and read. a0 rvdt a7 m0 m7 sq00 sq23 a0 m7 sck xlat redy trdt t ds t dh t swl t swh t lsd t slp t ss t bsp t slp t sld t sbd t ldr t rlp t rlp t lwl t ldr t sld or t lwh high-z d0/sq00 d15/sq23 fig. 5-2. write timing
?24 CXD2721Q-1 data section write begins after xlat rises, and here also transfer must be performed with lsb first, with t ds and t dh restrictions. in addition, after xlat rises at the starting point for sending to the data section, wait for 3 t + 20ns or more for the first sck rise ( t lsd ). when 16 bits (coefficient ram) or 24 bits (setup register) of this write is repeated, redy goes low within 4 t + 50ns, and the microcomputer is informed of waiting status for the sv cycle, which is the dedicated data rewrite cycle, by the microcomputer interface ( t sbd ). when redy goes high again, the corresponding data is written. the next communication can be restarted by using the redy signal as follows. when redy = low, sck can rise for the next transfer ( t bsp 3 20ns). similarly, when redy = low, xlat can fall for the next transfer ( t ldr 3 20ns). redy will fall due to this communication, but it is prohibited for xlat to rise for the next transfer before redy rises. be sure that the next xlat rises after redy rises ( t rlp 3 20ns). in order to restart the next transfer without using the redy signal, the following conditions must be observed. there should be 2 t + 40ns or more left between the sck rise for the final data section and the sck rise for the next transfer ( t ss ). similarly, xlat can fall for the next transfer after waiting 3 t + 20ns or more after the final data section sck rise ( t sld ). the t ss and t sld here are shorter times than t sbd 4 t + 50ns, so these are rather loose restrictions. however, even in this case the xlat rise for the next transfer must come after redy rises ( t rlp 3 20ns). further, the restriction for the xlat fall at the starting point of this write from t sld can be: t sld 3 3 t + 20ns if the preceding transfer was "write".
?25 CXD2721Q-1 (4)-2. read first, address and mode section data are transferred synchronized to sck, and xlat rises together with this. the procedure until this point is the same as for write, so the description is omitted here. read differs from write in that after xlat rises, redy falls within 3 t + 50ns ( t lbd ), and the microcomputer is informed of sv cycle waiting. at this time, the trdt pin changes from high-impedance status to active status ( t ldn 3 t + 80ns) simultaneously with the fall of redy. when the read data is ready, the redy pin changes from low to high. when the data read out from the trdt pin is made tr, and sck falls ( t rsdp 3 20ns) when the redy pin goes high, the first tr data is established within 2 t + 70ns ( t sdd ). the microcomputer reads this data at the sck rise. the tr data is read in order from the lsb with 16 bits for the coefficient ram and 24 bits for the setup register by adding sck. when all the corresponding data is read, read is completed. next, the method for restarting transfer after read is completed is described. as in case 1, there is a method for sending address and mode section data consecutively after reading all of the 16- or 24-bit data. 2 t + 40ns or more should be left between the sck rise for the final data read and the next sck rise ( t ss ), and this is established by the conditions t swl 3 1 t + 20ns and t swh 3 1 t + 20ns. further, at this read redy changes from high to low, but it is prohibited for the xlat for the next transfer to fall before this. if redy = low has been established, xlat can fall ( t ldr 3 20ns). also, while 16- or 24-bit data is being read from the trdt pin, address and mode section data writing to the rvdt pin for the next transfer can be started. in case 3, the final section of read data and the final data in the mode section overlap, and this allows shifting to the next transfer processing in the shortest possible time after data read. it is also possible to have data read and address and mode section write overlap partially, as shown by case 2.
