Therefore, pull-up pull-down should performed that potential unstable when this active. Shift clock serial data. Input data from RVDT taken according rise, output data from TRDT sent according fall.

Address section data transferred with first. Mode section data fixed bits regardless transfer contents. phase relationship between data (data applied RVDT pin) following restrictions: data must established before rises (tDS 20ns). data must held 20ns more after rises (tDH). itself following restrictions: level must 20ns more (tSWL). High level must also 20ns more (tSWH). After rises, which corresponds final mode section data, XLAT rises (tSLP 20ns). XLAT level width must maintained 20ns more (tLWL). Further, fall timing restrictions are: preceding transfer, REDY falls SCK, write, 20ns more required (tSLD). preceding transfer, REDY falls XLAT, read, 20ns more required (tLDR). Further, preceding transfers have been performed REDY Low, XLAT must wait REDY High before rising. procedure until this point same write read.

CXD2721Q-1
Data section write begins after XLAT rises, here also transfer must performed with first, with restrictions. addition, after XLAT rises starting point sending data section, wait 20ns more first rise (tLSD). When bits (coefficient RAM) bits (setup register) this write repeated, REDY goes within 50ns, microcomputer informed waiting status cycle, which dedicated data rewrite cycle, microcomputer interface (tSBD). When REDY goes High again, corresponding data written. next communication restarted using REDY signal follows. When REDY Low, rise next transfer (tBSP 20ns). Similarly, when REDY Low, XLAT fall next transfer (tLDR 20ns). REDY will fall this communication, prohibited XLAT rise next transfer before REDY rises. sure that next XLAT rises after REDY rises (tRLP 20ns). order restart next transfer without using REDY signal, following conditions must observed. There should 40ns more left between rise final data section rise next transfer (tSS). Similarly, XLAT fall next transfer after waiting 20ns more after final data section rise (tSLD). tSLD here shorter times than tSBD 50ns, these rather loose restrictions. However, even this case XLAT rise next transfer must come after REDY rises (tRLP 20ns). Further, restriction XLAT fall starting point this write from tSLD tSLD 20ns preceding transfer "write".
CXD2721Q-1
(4)-2. Read First, address mode section data transferred synchronized SCK, XLAT rises together with this. procedure until this point same write, description omitted here. Read differs from write that after XLAT rises, REDY falls within 50ns (tLBD), microcomputer informed cycle waiting. this time, TRDT changes from high-impedance status active status (tLDN 80ns) simultaneously with fall REDY. When read data ready, REDY changes from High. When data read from TRDT made falls (tRSDP 20ns) when REDY goes High, first data established within 70ns (tSDD). microcomputer reads this data rise. data read order from with bits coefficient bits setup register adding SCK. When corresponding data read, read completed. Next, method restarting transfer after read completed described. Case there method sending address mode section data consecutively after reading 24-bit data. 40ns more should left between rise final data read next rise (tSS), this established conditions tSWL 20ns tSWH 20ns. Further, this read REDY changes from High Low, prohibited XLAT next transfer fall before this. REDY been established, XLAT fall (tLDR 20ns). Also, while 24-bit data being read from TRDT pin, address mode section data writing RVDT next transfer started. Case final section read data final data mode section overlap, this allows shifting next transfer processing shortest possible time after data read. also possible have data read address mode section write overlap partially, shown Case
