39 / 66 page ![]() µµµµ PD64084 39 Data Sheet S16021EJ2V0DS 15.4 Serial Bus Registers The µ PD64084 incorporates twenty-four 8-bit write registers and seven 8-bit read registers. Writing to the write registers is possible in the write mode (with a slave in reception mode), while reading from the read registers is possible in the read mode (with a slave in transmission mode). The following table lists how each serial bus register is mapped. (1) Write register mapping Slave address: 10111000b = B8h (SLA0 = L), 10111010b = BAh (SLA0 = H) Data Map (SA00-SA17) SA D7 D6 D5 D4 D3 D2 D1 D0 00 0 NRMD 0 1 COUTS YAPS 01 CLKS NSDS MSS KILS 02 DYCOS EXADINS MFREEZE PECS EXCSS 03 0 CPP HDP CDL 04 DYCOR DYGAIN 05 DCCOR DCGAIN 06 YNRK YNRINV YNRLIM CNRK CNRINV CNRLIM 07 ID1ON ID1W0A1 ID1W0A2 CLK8OFF ST1S ST0S 08 WSC VTRH VTRR LDSR 09 WSS ID1DECON TH FELCHK TT VFLTH 0A VAPGAIN VAPINV 0B 0 0 YPFT YPFG 0C V1PSEL VEGSEL CC3N C0HS CLPH SELD2FH 0D 00 SELD1FL 0 010 1 0E 0000 100 0 0F 0100 010 0 10 YHCOR YHCGAIN ED2OFF OVST CSHDT KCTT 11 SHT0 SHT1 VCT OTT CLKG2D CLKGGT CLKGEB CLKGT 12 HPLLFS BPLLFS FSCFG PLLFG KILR 13 HSSL VSSL 14 BGPS BGPW 15 ADCLKS ADPDS NSDSW NRZOFF FSCOFF VTVH 16 SYSPDS EXTDYCO HIZEN VLSEL VLTYPE 0 0 17 CNROFS HCNTFSYN ADCLPFSW ADCLPSTP 0 0 0 0 Caution It may be necessary to change set values on the serial bus depending on the results of performance evaluation conducted by NEC Electronics. |
