TC9349AFG2006-02-2474(4) Serial operation condition settingz MASTER bit (Selection of external/internal SCK clock)Set the master or slave mode. Select the internal clock for the serial clock (SCK) to set the serial operation tomaster mode, and select the external clock to set the serial operation to slave mode.If the master setting is selected, the serial operation will start and the serial clock will be outputted when startsetting is made by the serial start bits (TSTA1 and TSTA2 bits), and the operation will stop under the serial counterstop condition. The serial clock selected by the clock selection bits (CK0, CK1 bit) will be outputted.If the slave setting is selected, the serial operation will start automatically when the external clock is inputted. Forthe 2- or 3-wired type, frequencies no higher than 200 kHz (fSCK) can be inputted as the external clock.Note: Select the slave setting when the UART is selected.Note: This bit is reset to “0” after a system reset.Selection of external or internal SCKclock (MASTER bit)0: External clock input (slave)1: Internal clock output (master)シリアルクロック(転送レート)周波数設定OSC1 OSC00 0CK1 CK00 00 11 01 12/3線式設定時クロック周波数(fSCK) UART送受信転送レート(fSCK)9600bpsモードfosc/2 -fosc/32bps18.75kHz37.5kHz9.375kHz4.6875kHzfosc/8bpsfosc/64bpsfosc/4fosc/8fosc/162400bpsモード1200bpsモード0 10 00 11 01 1fosc/275kHz150kHz37.5kHz18.75kHzfosc/4fosc/8fosc/169600bpsモードfosc/128bpsfosc/32bpsfosc/256bps2400bpsモード1200bpsモード19200bpsモードfosc/16bps010 00 11 01 1fosc/2112.5kHz225kHz56.25kHz28.125kHzfosc/4fosc/8fosc/169600bpsモードfosc/192bpsfosc/48bpsfosc/384bps2400bpsモード1200bpsモード19200bpsモードfosc/24bps10 00 11 01 1fosc/275kHz150kHz37.5kHz300kHzfosc/4fosc/8fosc/169600bpsモードfosc/64bpsfosc/32bpsfosc/256bps 2400bpsモード1200bpsモード19200bpsモードfosc/512bps1発振器の設定低速発振器(75kHz)高速発振器(300kHz)高速発振器(450kHz)高速発振器(600kHz)2344bps9375bps1172bps2344bps9375bps1172bps18750bps2344bps9375bps1172bps18750bps2344bps9375bps1172bps18750bpsシリアルクロック(SCK)シリアル入出力(SDIO)2/3線式設定時 fSCKUART入出力(TX/RX)tSCKUART設定時Serial clock (transmission rate) frequency settingOscillatorsettingLow-speedoscillator(75kHz)High-speedoscillator(300kHz)High-speedoscillator(450kHz)High-speedoscillator(600kHz)UART transmission rate (fSCK)2- or 3-wired modeSerial clock (SCK)Serial input/output (SDIO)UART modeUART input/output (TX/RX)modemodemodemodemodemodemodemodemodemodemodemodemodemodemode2- or 3-wired interface clockfrequency (fSCK)
