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

Data section write begins after XLAT rise, here also transmission must with first, with restrictions. addition, after raising XLAT starting point sending data section, wait 20ns more first rise. (tLSD) When bits (coefficient RAM) bits (setup register) this write repeated, REDY 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 restarts using REDY signal follows. When REDY Low, next transmission rise (tBSP 20ns same way, when REDY Low, XLAT next transmission fall (tLDR 20ns). REDY will fall this transmission, prohibited XLAT rise next transmission before REDY rises. sure raise next XLAT after REDY rises (tRLP 20ns order restart next transmission without using REDY signal, following conditions must observed: There should 40ns more left between rise final data section rise next transmission (tSS). same way, XLAT next transmission fall after waiting 20ns more after final data section rise (tSLD). tSLD here shorter times than tSBD 50ns, restriction conditions much strict. However, even this case rise XLAT next transmission must come after REDY rise (tRLP 20ns). Further, restriction XLAT fall starting point this write from tSLD tSLD 20ns preceding transmission "write".
CXD2720Q-2
(4)-2. Read First, address section mode section data transmitted synchronized SCK, XLAT raised matched with this; procedure until this point same write, description omitted here. Read differs from write that after XLAT rise, REDY falls within 50ns (tLBD), microcomputer informed cycle waiting. this time, TRDT changes from high-impedance state active state (tLDN 80ns) simultaneously with REDY fall. When read data ready, REDY changes from High. When data read from TRDT made falls (tRSDP 20ns) when REDY goes High, first data defined within 70ns (tSDD). microcomputer reads this data rise. data read order from with bits coefficient bits setup register adding SCK, corresponding data read, then read completed. Next, method restarting transmission after read completed described. Case there method sending address section mode section data consecutively after reading 24-bit data. There should 40ns more 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 transmission fall before this. REDY been verified, XLAT fall (tLDR ns). Also, while 24-bit data being read from TRDT pin, address mode section data writing RVDT next transmission started. Case final section read data final data mode section overlap, this allows shifting next transmission processing shortest possible time after data read. also possible have data read address mode section write overlap partially, shown Case

Also, algorithm such that allophones will generated even when nRpR setting value changed. This applies nRpR_R (Rch pitch ratio). Common Setting Independent Setting Pitch Ratio pitch ratio value commonly independently Rch. recommended that common value when controller used music controller, independent values when used voice effect.
